MH8S64DALD -6,-7,-8
536870912 -BIT (8388608 - WORD BY 64-BIT)Synchronous DRAM
DESCRIPTION
The MH8S64DALD is 8388608 - word by 64-bit
Synchronous DRAM module. This consists of eight
industry standard 8Mx8 Synchronous DRAMs in
TSOP and one industory standard EEPROM in
TSSOP.
The mounting of TSOP on a card edge Dual
Inline package provides any application where
high densities and large quantities of memory are
required.
This is a socket type - memory modules, suitable
for easy interchange or addition of modules.
