Description
The V437432E24V memory module is organized
33,554,432 x 72 bits in a 168 pin dual in line
memory m odule (DIMM). The 32M x 72 registered
DIMM uses 9 Mosel-Vitelic 32M x 8 ECC SDRAM.
The x72 modules are ideal for use in high
performance computer systems where increased
memory densityand fastaccess timesare required.
