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..
