System and method for storing data in a non-volatile memory including a multi-level cell and single-level cell memory portions. To write a dataset to the non-volatile memory, if the size of the dataset is equal to the size of pages in the multi-level cell memory portion, the dataset may be written directly to the multi-level cell memory portion to fill an integer number of pages in a single write operation. However, if the size of the dataset is different than the size of the multi-level cell memory pages, at least a portion of the dataset may be temporarily written to the single-level cell memory portion until data is accumulated in a plurality of write operations having a size equal the size of the multi-level cell memory pages. The accumulated data may fill an integer number of the pages in the multi-level cell memory portion in a single write operation.

A traffic manager for a network switch input or output port stores incoming cells in a cell memory and later sends each cell out of its cell memory toward one of a set of forwarding resources such as, for example, another switch port or an output bus. Data in each cell references the particular forwarding resource to receive the cell. Each cell is assigned to one of several flow queues such that all cells assigned to the same flow queue are to be sent to the same forwarding resource. The traffic manager maintains a separate virtual output queue (VOQ) associated with each forwarding resource and periodically loads a flow queue (FQ) number identifying each flow queue into the VOQ associated with the forwarding resource that is to receive the cells assigned to that FQ. The traffic manager also periodically shifts an FQ ID out of each non-empty VOQ and forwards the longest-stored cell assigned to that FQ from the cell memory toward its intended forwarding resource. The traffic manager separately determines the rates at which it loads FQ IDs into VOQs and the rates at which it shifts FQ IDs out of each non-empty VOQ. Thus the traffic manager is able to separately control the rate at which cells of each flow queue are forwarded and the rate at which each forwarding resource receives cells.

The present invention provides a program method of a flash memory device including a plurality of memory cells for storing multi-bit data indicating one of a plurality of states. The memory cells are subjected to a primary program operation. Those memory cells arranged within a specific region of respective states are subjected to a secondary program operation to have a threshold voltage equivalent to or higher than a verify voltage used in the primary program operation. Thus, although a threshold voltage distribution is widened due to an electric field coupling/F-poly coupling and HTS, a read margin between adjacent states may be sufficiently secured using the program method.

Disclosed is an apparatus and method for performing power saving control of a mobile terminal, which includes a battery capacity measurement unit, an input unit, a memory and a controller. Using the input unit, the user specifies a power saving mode type of the terminal and sets a power saving mode and power saving mode items corresponding to the specified power saving mode type. The memory stores information of the set power saving mode and the set power saving mode items in association with the specified power saving mode type. The controller performs power saving control corresponding to the set power saving mode items if battery capacity measured by the measurement unit is less than or equal to a preset battery capacity. The user can actively select how the terminal performs the power saving control, in their desired manners according to the remaining battery capacity.

To use the memory space more effectively, cell memory can be shared by an input link and all output links. To prevent one flow from occupying the entire memory space, a threshold may be provided for the queue. The queue threshold may accommodate the RTT delay of the link. Queue length information about a downstream switch module may be sent to an upstream switch module via cell headers in every credit update period per link. Cell and/or credit loss may be recovered from. Increasing the credit update period reduces the cell header bandwidth but doesn't degrade performance significantly. Sending a credit per link simplifies implementation and eliminates interference between other links.

Fabrication methods using Ion Beam Etching (IBE) for MRAM cell memory elements are described. In embodiments of the invention the top electrode and MTJ main body are etched with one mask using reactive etching such as RIE or magnetized inductively coupled plasma (MICP) for improved selectivity, then the bottom electrode is etched using IBE as specified in various alternative embodiments which include selection of incident angles, wafer rotational rate profiles and optional passivation layer deposited prior to the IBE. The IBE according to the invention etches the bottom electrode without the need for an additional mask by using the layer stack created by the first etching phase as the mask. This makes the bottom electrode self-aligned to MTJ. The IBE also achieves MTJ sidewall cleaning without the need for an additional step.
