The MCM72JG32 and MCM72JG64 are designed to provide a burstable, high performance, 256K/512K L2 cache for the Pentium microprocessor in conjunction with Intel’s Triton chip set. The modules are configured as 32K x 64 and 64K x 64 bits in a 160 pin card edge memory module. Each module uses four of Motorola’s 5 V 32K x 18 or 64K x 18 BurstRAMs and one Motorola 5 V 32K x 8 FSRAM for the tag RAM.
