Part Number : 81C4256A-70
Function : CMOS 256K x 4 BIT FAST PAGE MODE DYNAMIC RAM
Manufacturers : Fujitsu
The Fujitsu MB81C4256A is a CMOS, fully decoded dynamic RAM organized as
262,144 words x 4 bits. The MB81C4256A has been designed for mainframe
memories, buffer memories, video image memories requiring high speed and
high-band width output with low power dissipation, as well as for memory systems
of handheld computers which need very low power dissipation.
Fujitsu’s advanced three-dimensional stacked capacitor cell technology gives the
MB81C4256A highα-ray soft error immunity and extended refresh time. CMOS
technology is used in the peripheral circuits to provide low power dissipation and
high speed operation..
