ABSTRACT:
An improved circuit is provided for extending the write-recovery time of a high speed memory into the next memory access cycle. In the preferred embodiment, the address buffer circuits turn off at a suitable high rate for read but are controlled to turn off more slowly for a write and to thereby extend the write select signal. In a specific address buffer circuit, FETs are supplied a reduced drain-source current during write and thereby are made to switch at a suitably slower speed.
