In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes (640 × 1024 bytes) of the memory on IBM PC or compatible systems. It is the read-write memory directly addressable by the processor for use by the operating system and application programs. As memory prices rapidly declined, this design decision became a limitation in the use of large memory capacities until the introduction of operating systems and processors that made it irrelevant.
Non-volatile memory with synchronous DRAM interface
InactiveUS20050204091A1Easy accessSimplifies design effortMemory architecture accessing/allocationDigital storageConventional memoryHigh density
A high density non-volatile memory system, card, and device is described that incorporates a synchronous interface. This is accomplished through use of an external or embedded controller and / or memory buffer to manage the high density non-volatile memory device(s) to present it as a conventional memory device having a synchronous interface that is accessible by row and column address. This allows the high density non-volatile memory to support in-place code execution and allows it to be booted from. Additionally, this incorporation eliminates the overhead of drivers and / or operating system support required to utilize and present conventional high density non-volatile memory devices and moves it internal to the memory device. This simplifies the use and design effort in the overhead and specialized interfacing of high density non-volatile memories and in particular, NAND architecture Flash memories, while reducing the production cost through use of less expensive high density non-volatile memory.

An apparatus and method are described for identifying uncommitted memory in a system RAM during an initialization process of a computer system, such as a boot procedure or power-on self test, during which memory management is uncontrolled. In various embodiments of the invention, repeating patterns that are indicative of uncommitted memory blocks are identified within a conventional memory area of the system RAM. At least some of the uncommitted memory blocks are allocated for use by an option ROM or other BIOS data and a table is created identifying these uncommitted memory blocks. After the BIOS code exits the system RAM, the table is used to restore the uncommitted memory blocks into their previous data states.

An improved memory module and method of manufacture are presented. The memory module takes on the same outer dimensions as conventional memory cards. The memory module includes an integrated circuit and a conductor encased within molded resin. The conductor can be taken from a tape or a lead frame, and can include bumps or wires extending from the conductor to corresponding bonding pads on the integrated circuit. The bonded integrated circuit can thereafter be placed within a cavity formed inside a mold housing, where resin may be injected to form the memory module. The conductor can also be shaped so as to extend on multiple planes from the connection point on or near the bonding pad to an edge connector residing near one edge only of the memory module.

Flash memory and program verify method for flash memory
ActiveUS20050286299A1Improve reliabilityExclude influenceRead-only memoriesDigital storageConventional memoryBit line
In conventional memory arrays in which a bit line is shared by memory cells, a cell current flows over into neighbor cell(s) in a program verify process, and therefore, the threshold of a memory cell to be programmed is erroneously determined to be lower. Therefore, in a program verify process, a control circuit 3 writes a fail value to a neighbor cell buffer 5 when all neighbor cell(s) having an offset of n or less from a memory cell to be programmed are in the erased state, and when otherwise, writes a pass value to the neighbor cell buffer 5. The control circuit 3 verifies input write data and also verifies data stored in the neighbor cell buffer(s). In the latter verify process, a verify voltage higher than an ordinary one is used to compensate for the leakage of cell current.

Data bus inversion using spare error correction bits
In a memory system, a spare error correction bit is produced by processing data to be stored in sufficiently large chunks that the number of error correction bits required to protect each chunk are fewer than the available error correction signal lines on a memory bus and storage device. The spare bit is then used for an inversion bit in a parallel data bus inversion scheme, wherein data is selectively inverted to minimize bus switching. The transmission of data and error correction bits are spread over multiple phases, wherein parallel data bus inversion is applied to each phase. Alternatively, the transmission of data and error correction bits may be transmitted and stored in a single transaction. In either case, the spare bit is transmitted on a conventional memory bus and stored in a conventional memory module along with data and error correction bits.

A memory test device that issues a test pattern read request to a memory, captures test pattern signals placed by the memory on a data input / output bus in response to the test pattern read request, and compares the test pattern signals with their expected values. This can solve a problem involved in a conventional memory test device in that because the pin width of data pins is narrower than the bus width of the data input / output bus that connects a memory and a data bus controller, even if the memory reads test pattern signals in accordance with the width of the data input / output bus, the test pattern signals cannot be sent to the tester without being divided, and hence the tester cannot achieve the quick test of the memory.
