An electro-optic display, having at least one pixel capable of achieving any one of at least four different gray levels including two extreme optical states, is driven by displaying a first image on the display, and rewriting the display to display a second image thereon, wherein, during the rewriting of the display, any pixel which has undergone a number of transitions exceeding a predetermined value without touching an extreme optical state, is driven to at least one extreme optical state before driving that pixel to its final optical state in the second image.

A system and method for virtual link aggregation for combining network links of various types and speeds to increase throughput and reliability for packetized transport. In contrast with physical port trunking, the system does not require direct control over ports or network interfaces. Instead, the system rewrites packet addresses and works through existing networking equipment, without requiring any new or special protocols, processing, or equipment within the network. The system works through low-level rerouting by rewriting hardware addresses and/or high-level routing by rewriting logical addresses. Thus packets are redirected through multiple routes to a common destination via alternate gateways and links. Different algorithms may be employed to balance the load on each link and determine an optimal route for each packet. Embodiments may also employ packet flow or stream identification and thereby only provide link aggregation for a specified set of packet flows.

The number of times of rewriting of memory cells is stored by number of rewrite (EW) times storage section. In data rewriting to memory cells, number of rewriting times data of a selected memory cell is transferred to and latched in a number of EW times sense latch section and transferred to a number of EW times counter. Controlling processor (CPU) sets a condition on a write pulse on the basis of a value obtained by updating a count value of the number of EW times counter and controls the operation of rewriting. In data rewriting, a count value after update of the number of EW times counter is transferred to the number of EW times sense latch section. The updated number of rewritings is transferred to a corresponding number of EW times storage section, in parallel to data rewriting to a memory cell.

The invention provides a balance method for circulatory rewriting and flashing used in a solid state disc. During each operation, new data are written in a physical block which is used seldom, and the physical block is called a main block; when the data needs to be replaced, the renewed data are written in another new physical block, and the physical block is called a replacement block; when the replacement block is fully written, the effective data in the main block and the effective data in the replacement block are transported to a new physical block, and the new physical block is a new main block; and the previous main block and the previous replacement block are chained to a waste block chain. By adopting the method provided by the invention, the storage mediums of the entire solid state disc lose evenly and the balance of the erasable time of each block when the data blocks are chosen by write data is ensured, thereby prolonging the service life of the solid state disc.

In a semiconductor device, a phase change layer is formed as a side wall and is therefore reduced in volume. Even if the number of times of rewriting is small, the phase change layer is entirely used as a phase change region. Therefore, the phase change region is not increased in volume even if the number of times of rewriting is increased. Since the volume of the phase change region is not changed, an electric current level required for rewriting is constant. Thus, the semiconductor device having a memory cell capable of carrying out stable rewriting is obtained.

The invention discloses a fragment rewriting method for a data repetition removing system. A cache as a rewriting sensing cache is added in data removing; data items in the rewriting sensing cache are container identifications referenced by a data block; and if the container identifications referenced by the data block which is confirmed as a data fragment are stored in the rewriting sensing cache, data are not required to be rewritten, or else, the data fragment is required to be rewritten. According to the fragment rewriting method, the cache of which the time is the same with the reading time of the data and the cache strategies are the same is added in the data repetition removing process, unnecessary repeated data block rewriting is avoided, and the shortcoming of the existing arithmetic is overcome. Compared with the existing fragment removing arithmetic, the fragment rewriting method has the advantages that influence on reading performance due to the data fragment is reduced, and the reading performance is improved by rewriting the data fragment; and less repetition rate loss is guaranteed while the reading performance is improved.

A memory rewriting apparatus can rewrite control programs for a vehicle mounted ECU through communications reliably and easily. A transmission and reception circuit communicates with a data communications device that sends program data. An ID check circuit checks based on an ID check code attached to the data whether a subject vehicle on which the apparatus is installed is a vehicle to be rewritten. A communications condition determination device determines whether the communications condition is suitable for communications. A control part (MPU) controls writing program data into a memory of the vehicle mounted ECU. The control part notifies the non-completion of rewriting to the data communications device when determined, before and during data rewriting, that the communications condition is unsuitable, and it also notifies the completion of rewriting to the data communications device after the rewriting of the data has been completed, when determined that the communications condition is suitable.

A cache with a database system that contains a subset of the objects stored in another database system. The cache database system responds to a request that contains a reference to an object that is not in the cache by redirecting the request to the other database system when the request is executed in the cache's database system. Redirection is done by rewriting requests that refer to objects that are not in the cache. In one kind of rewriting, a cursor is marked to indicate redirection, and when the cursor is executed in the cache database system, it is redirected to the other database system for execution. In the other kind, calls to stored procedures that are not present in the cache database system are rewritten as remote procedure calls to the stored procedures in the other database system.

A BIOS updating section installs a BIOS update file which operates on an OS and to which a one-time rewriting program is added to write the one time rewriting program in a second program area of a flash ROM. A BIOS executing section checks whether the one time rewriting program is stored in the nonvolatile memory during the execution of the BIOS or not and rewrites the BIOS setting information of a second nonvolatile memory by executing the one time rewriting program when the one time rewriting program is stored. The one time rewriting program is erased when the rewriting of the BIOS setting information has been normally finished.

In an RF tag, a mask ROM or a flash memory is used for storing data such as an ID number. Although the mask ROM can be realized at a low price, rewriting is not possible. In addition, in the flash memory, although electric rewriting is possible, production cost increases. Accordingly, it is difficult to provide an RF tag by which data rewriting is possible at a low price. An RF tag is provided with a power supply circuit having a function to generate a power supply voltage from a weak radio signal and a memory which can hold data stored in a data holding portion by the power supply voltage. With the above structure, a high-performance RF tag capable of rewriting data such as an ID number after production can be provided at a low price.

The application layer is used for realizing a specific-application user interface; the intermediary business layer is used for supporting a function support program for the specific application; the drive adaptation layer is used for supporting a device drive function interface for the function support program; the operation system layer is used for realizing the task scheduling on the function call conducted by the function support program through device drive function interface; and the hardware drive layer is used for realizing the hardware drive of the digital television set-top box for the task scheduling. The software platform overcomes the problem that a set-top box software based on a hardware platform is migrated to a set-top box based on different hardware platforms, so that the rewriting of the software is caused and the high cost is brought to the factory because of different hardware platforms.

The service life of memory cards is to be substantially elongated against the occurrence of faulty blocks. A control logic searches blocks in a nonvolatile memory cell array for any acquired fault on the basis of a fault-inviting code in a management information section. If any faulty block is detected, the faulty block will be subjected to write/read comparison of data to judge whether or not the data in the block are normal. Any block determined to be normal will undergo rewriting of its fault-inviting code and registered as a normal block. Further, the registered block is stored into a write management table in the management area as a writable block. This enables an essentially normal block judged faulty on account of an erratic error or some other reason to be restored.

A technique for implementing a data processor to determine if an exception has been thrown. Specifically, the technique may be used in an interpretive environment where a table known as a bytecode (upcode) dispatch table is used. The dispatch table contains addresses for code that implements each bytecode. When the interpreter executes normally, these addresses point to the basic target machine code for executing each bytecode. However, when an Asynchrounously Interrupted Exception (AIE) is thrown, then the dispatch table is repopulated so that all byte codes point to routines that can handle the exception. These may point to a routine, such as an athrow, that has been extended to handle the special case of the AIE. Alternatively, the rewritten table can point to a routine that is specifically written to handle the firing of an AIE. The table contents are restored to their prior state once the exception handling is complete. The scheme may also be implemented non-rewriting of the table if a thread is in a non-Asynchronous Transfer of Control (to defer ATC) deferred state.
