Abstract :
A 4-Mb SRAM with a 15-ns access time and a uniquely selectable (×4 or ×1) bit organization has been developed based on a 0.55-μm triple-polysilicon double-metal CMOS technology. An input-controlled PMOS-load (ICPL) sense amplifier, Y-controlled bit-line loads (YCLs), and a transfer word driver (TDW) are three key circuits which have been utilized in addition to the 0.55-μm CMOS technology to achieve the remarkable access time of 15 ns. Bit organization of either ×4 or ×1 can be selected purely electrically, and does not require any pin connection procedure
