MH4V64/644AXJJ-5,-6,-5S,-6S
FAST PAGE MODE 268435456-BIT (4194304-WORD BY 64-BIT)DYNAMIC RAM
DESCRIPTION
This is family of 4194304 - word by 64 - bit dynamic RAM
module. This consists of four industry standard 4Mx16 dynamic
RAMs in TSOP and one industry EEPROM in TSSOP.
The mounting of TSOP on a card edge dual in line package
provides any application where high densities and large of
quantities memory are required.
This is a socket-type memory module,suitable for easy
interchange of addition of modules.
