The Hitachi HM514400B/BL, HM514400C/CL
are CMOS dynamic RAM organized 1,048,576-
word
×
4-bit. HM514400B/BL, HM514400C/CL
have realized higher density, higher performance
and various functions by employing 0.8
μ
m CMOS
process technology and some new CMOS circuit
design technologies. The HM514400B/BL,
HM514400C/CL offer Fast Page Mode as a high
speed access mode. Multiplexed address input
permits the HM514400B/BL, HM514400C/CL to
be packaged in standard 300-mil 26-pin plastic
SOJ, standard 400-mil 20-pin plastic ZIP and 26-
pin plastic TSOP II.
