Advance Information

4M Late Write HSTL

The MCM69L736A/818A is a 4M synchronous late write fast static RAM

designed to provide high performance in secondary cache and ATM switch,

Telecom, and other high speed memory applications. The MCM69L818A

(organized as 256K words by 18 bits) and the MCM69L736A (organized as 128K

words by 36 bits) are fabricated in Motorola’s high performance silicon gate

BiCMOS technology.

The differential clock (CK) inputs control the timing of read/write operations of

the RAM. At the rising edge of CK, all addresses, write enables, and synchronous

selects are registered. An internal buffer and special logic enable the memory to

accept write data on the rising edge of CK a cycle after address and control

signals. Read data is available at the falling edge of CK.

The RAM uses HSTL inputs and outputs. The adjustable input trip–point (Vref)

and output voltage (VDDQ) gives the system designer greater flexibility in

optimizing system performance.

The synchronous write and byte enables allow writing to individual bytes or the

entire word.

The impedance of the output buffers is programmable, allowing the outputs to

match the impedance of the circuit traces which reduces signal reflections.
