Description

The MH8S72DALD is 8388608 - word by 72-bit Synchronous DRAM module. This consists of nine 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 of MH8S72DALD provides any application where high densities and large quantities of memory are required.

MH8S72DALD is a socket type - memory modules, suitable for easy interchange or addition of modules.
