Abstract :
A low power multi-port SRAM design method based on banks switchable between active and standby mode is described. Speed decrease is prevented by use of an access method with hidden precharge-time. More than 56% power reduction can be achieved when 64 banks are used to implement a 4-port SRAM. A 4 kB SRAM with 4 ports and 16 banks has been designed and fabricated for verification.
