    摘要: A memory device including memory cells and edge cells is described. In one example, the memory device includes: an array of memory cells used for data storage; a plurality of first edge cells not used for data storage; and a plurality of second edge cells not used for data storage. The plurality of first edge cells and the plurality of second edge cells are arranged respectively at two opposite sides of the array of memory cells. At least one edge cell, among the plurality of first edge cells and the plurality of second edge cells, comprises a circuit configured for controlling the array of memory cells to enter or exit a power down mode.

    摘要: Systems and methods are provided for controlling power down of an integrated dual rail memory circuit. The power down system is configured to power down the power rail for input and logic components (VDD) while maintaining power to the power rail for the memory cells (VDDM). The power down system includes two voltage rails, a clock generator, and a power detector for detecting the power on VDD. The power detector generates an isolated power signal when voltage on VDD is below a voltage threshold. The isolated power signal is configured to disable the clock generator and thus reduce dynamic power as the read/write cycle is not triggered during power down.

    摘要: Methods, devices, arrays and systems for reducing standby power for a floating body memory array. One method includes counting bits of data before data enters the array, wherein the counting includes counting at least one of: a total number of bits at state 1 and a total number of all bits; a total number of bits at state 0 and the total number of all bits; or the total number of bits at state 1 and the total number of bits at state 0. This method further includes detecting whether the total number of bits at state 1 is greater than the total number of bits at state 0; setting an inversion bit when the total number of bits at state 1 is greater than the total number of bits at state 0; and inverting contents of all the bits of data before writing the bits of data to the memory array when the inversion bit has been set.

    摘要: A memory device has a memory array of a plurality of memory cells arranged in a plurality of columns and a plurality of rows. The memory cells in each of the plurality of columns include first memory cells and second memory cells alternately arranged along a column direction of the plurality of columns. A first computation circuit is coupled to the first memory cells in each of the plurality of columns, and is configured to generate first output data corresponding to a first computation performed on first weight data stored in the first memory cells. A second computation circuit is coupled to the second memory cells in each of the plurality of columns, and is configured to generate second output data corresponding to a second computation performed on second weight data stored in the second memory cells.
