SONY ΣRAM^™CXK79M72C160GB / CXK79M36C160GB 33/4/5

18Mb 1x1Lp HSTL High Speed Synchronous SRAMs (256Kb x 72 or 512Kb x 36)

Preliminary

Description

The CXK79M72C160GB (organized as 262,144 words by 72 bits) and the CXK79M36C160GB (organized as 524,288 words

by 36 bits) are high speed CMOS synchronous static RAMs with common I/O pins. They are manufactured in compliance with

the JEDEC-standard 209 pin BGA package pinouts defined for SigmaRAM^™devices. They integrate input registers, high speed

RAM, output registers, and a two-deep write buffer onto a single monolithic IC. Single Data Rate (SDR) Pipelined (PL) read

operations and Late Write (LW) write operations are supported, providing a high-performance user interface. Positive and neg-

ative output clocks are provided for applications requiring source-synchronous operation.

All address and control input signals are registered on the rising edge of the CK differential input clock.

During read operations, output data is driven valid once, from the rising edge of CK, one full cycle after the address and control

signals are registered.

During write operations, input data is registered once, on the rising edge of CK, one full cycle after the address and control

signals are registered.

Output drivers are series-terminated, and output impedance is programmable via the ZQ control pin. When an external resistor

RQ is connected between ZQ and V_SS, the impedance of the SRAM’s output drivers is set to ~RQ/5.

300 MHz operation (300 Mbps) is obtained from a single 1.8V power supply. JTAG boundary scan interface is provided using

a subset of IEEE standard 1149.1 protocol.
