Description
The V437464S24V m emory module is organized
67,108,864 x 72 bits in a 168 pin dual in line
memory module (DIMM). The 64M x 72 unbuffered
DIMM uses 18 Mosel-Vitelic 32M x 8 ECC SDRAM.
The x72 modules are ideal for use in high
performance computer systems where increased
memory density andfast accesstimes are required.
