256KB and 512KB BurstRAM Secondary Cache Module for Pentium

The MCM72CB32SG and MCM72CB64SG are designed to provide a burstable, high performance, 256K/512K L2 cache for the Pentium microprocessor. The modules are configured as 32K x 72 and 64K x 72 bits in a 160 pin card edge memory module. The module uses four of Motorola’s MCM67C518 or MCM67C618 BiCMOS BurstRAMs.
