    摘要: A representative memory device includes a cell array, at least one break cell that subdivides the cell array into bit cell arrays, and one or more power switches that are electrically coupled to the bit cell. In one embodiment, the break cell separates a connectivity of a first voltage and a second voltage between at least two bit cell arrays so that the bit cell arrays can be selectively coupled to either the first voltage or the second voltage using the power switches. The power switches control the connection of each separated bit cell array of the cell array to either the first voltage or second voltage.

    摘要: An integrated circuit includes a static random access memory (SRAM) array coupled to a first voltage supply node and a second voltage supply node. The first and second voltage supply nodes provide a retention voltage across the SRAM array. A current limiter is disposed between the SRAM array and the first voltage supply node, and a voltage regulator is coupled in parallel with the current limiter between the SRAM array and the first voltage supply node. The voltage regulator is configured to maintain the retention voltage across the SRAM array above a predetermined level.
