Abstract
In described embodiments, a memory circuit includes a static random access memory (SRAM) including N banks of memory cells, rows of M sense amplifiers, a controlled feedback latch storing a previous state of input data in a read cycle, a pull down select block coupled to the controlled feedback latch and the dummy sense amplifier, a dummy output latch coupled to the pull-down select block to store the read data, and a SRAM reset generation circuit coupled to the sense amplifier control circuits and the controlled feedback latch. The dummy output latch is a latch that is the same as a sense amplifier latch used in the local input/output circuit, thereby, no margin is involved between a reset of the sense amplifiers and the read data latched at the dummy output latch in the read cycle.
