HM621400HC Series 4M High Speed SRAM (4-Mword × 1-bit) ADE-203-1199 (Z) Preliminary Rev. 0.0 Nov. 30, 2000 Description The HM621400HC is a 4-Mbit high speed static RAM organized 4-Mword × 1-bit. It has realized high speed access time by employing CMOS process (6-transistor memory cell)and high speed circuit designing technology. It is most appropriate for the application which requires high speed and high density memory, such as cache and buffer memory in system. The HM621400HC is packaged in 400-mil 32-pin SOJ for high density surface mounting. Features • Single 5.0 V supply: 5.
