A dual function hybrid memory cell is disclosed. In one aspect, the memory cell includes a substrate, a bottom charge-trapping region formed on the substrate, a top charge-trapping region formed on the bottom charge-trapping region, and a gate layer formed on the top charge trapping region. In another aspect, a method for programming a memory cell having a substrate, a bottom charge-trapping layer, a top charge-trapping layer, and a gate layer is disclosed. The method includes biasing a channel region of the substrate, applying a first voltage differential between the gate layer and the channel region, injecting charge into the bottom charge-trapping layer from the channel region based on the first voltage differential. The method also includes applying a second voltage differential between the gate layer and the channel region and injecting charge from the bottom charge-trapping layer into the top charge-trapping layer based on the second voltage differential.

A method and arrangement for queuing data in a prioritized manner have a queue with a single queue write side in which data entries are input to the queue. The queue also has a plurality of queue read sides, with each read side having a different priority level. An entry exiting from the queue write side is examined to determine the priority level of the entry, and then placed into the queue read side with the matching priority level as the entry. The queue read sides form the output of the queue, and are polled and emptied so that the higher priority queues are emptied completely before emptying lower priority queues.

A memory system comprises a memory including a plurality of bits arranged as one or more words. Each bit in each word is capable of being programmed either to a particular logical state or to another logical state. A variable data width controller is in communication with the memory. The variable data width controller comprises an adder to determine a programming number of bits in a word to be programmed into a memory. Each bit to be programmed is in the particular logical state. A partitioning block divides the word in to two or more sub-words when the programming number exceeds a maximum number. A switch is in communication with the partitioning block. The switch sequentially provides one or more write pulses. Each write pulse enables a separate communication path between the memory and one of the word and the sub-words.

A synchronous flash memory includes an array of non-volatile memory cells. The memory device has a package configuration that is compatible with an SDRAM. In one embodiment, the synchronous memory device comprises an array of memory cells arranged in rows and columns. A clock connection is provided to receive an externally provided clock signal. The memory does not require a precharge time period during a time period between the first and second externally provided active commands.
摘要:
A method and arrangement for maintaining a time order of entries in a memory determines a row in which the entry will be stored, the memory being logically divided into rows and columns. The columns are arranged sequentially in each row from the newest to the oldest. Once the row in which the entry will be stored is determined, the entry is stored in that row in the column (or entry location) that is the newest column. The entry that was previously in the newest column is shifted to the next older column, and the entry that was previously in the next older column is shifted to the next most older column, etc. If a row is completely filled prior to the writing of a new entry, then the entry in the oldest column is removed from the memory and the other entries shifted.

Circuitry for performing a memory block write is described. The memory block includes b block words, each block word having t block bytes. Each block byte has s bits of memory. Each block byte is associated with at least two associated mask value bits. A constant register has at least s x t bits of memory arranged as t constant bytes, each constant byte storing a constant value, each constant byte associated with one block of every block word. The block write circuitry includes control circuitry for selecting one of a normal write function and a block write function in accordance with a block write signal. When the block write function is selected, the control circuitry stores the associated constant value in every nonmasked block byte substantially simultaneously in accordance with a value of the associated mask value bits.
