Abstract
A memory device and an operation method thereof is disclosed. The memory device includes a static random access memory (SRAM) cell, a power-supply assist-voltage generator circuit, a source assist-voltage generator circuit, and a word-line assist-voltage generator circuit. The power-supply assist-voltage generator circuit, the source assist-voltage generator circuit, and the word-line assist-voltage generator circuit lower the effective supply voltage for un-accessed rows of memory cells in the hold mode, increase the effective supply voltage for accessed memory cells in the active mode, and lower the effective supply voltage further for all the SRAM cells in the standby mode to achieve a solution for active and standby power reduction besides achieving the stability and noise margins.
