ABSTRACT:
An MOS memory cell of the static type employs a pair of cross-coupled driver transistors forming a bistable circuit, with load resistors replaced by a pair of series coupling transistors connecting storage nodes to complementary precharged data lines. The coupling transistors are turned on in sequence, for refresh, so an intermediate node is charged during a first phase and discharged into the storage nodes during the second phase. Both transistors are turned on at the same time for read or write operations.
