Static random access memory with rewriting circuit

摘要

A static random access memory for improving the cell stability during read/write operation is provided. The SRAM comprises: a bit line and an inverted bit line; a memory cell coupled between the bit line and the inverted bit line for storing data; and a re-writing circuit coupled between the bit line and the inverted bit line for re-writing the data stored in the memory cell to the memory cell, in response to, at least, one read/write control signal for controlling read/write operation of the memory cell. The SRAM of this invention can be stably operated under low power voltage and/or at low temperature.
