The MCM72BA32SG and MCM72BA64SG are designed to provide a burstable,high performance, 256K/512K L2 cache for the Pentium microprocessor.
The modules of the MCM72BA32 are configured as 32K x 72 and 64K x 72 bits in a 136 pin dual readout single inline memory module (DIMM). The module uses four of Motorola's MCM67B518 or MCM67B618 BiCMOS BurstRAMs. Bursts can be initiated with either address status processor (ADSP) or address status controller (ADSP). Subsequent burst addresses are generated internal to the BurstRAM by the burst advance (ADV) input pin.
