Features

Functional Description

• Register-Register Late Write mode, Pipelined Read mode

• 2.5 V +200/–200 mV core power supply

• 1.5 V or 1.8 V HSTL Interface

• ZQ controlled programmable output drivers

• Dual Cycle Deselect

Because GS815018/36A are synchronous devices, address data

inputs and read/write control inputs are captured on the rising

edge of the input clock. Write cycles are internally self-timed

and initiated by the rising edge of the clock input. This feature

eliminates complex off-chip write pulse generation required by

asynchronous SRAMs and simplifies input signal timing.

• Fully coherent read and write pipelines

• Byte write operation (9-bit bytes)

• Differential HSTL clock inputs, K and K

• Asynchronous output enable

• Sleep mode via ZZ

GS815018/36A support pipelined reads utilizing a rising-edge-

triggered output register. They also utilize a Dual Cycle

Deselect (DCD) output deselect protocol.

• IEEE 1149.1 JTAG-compliant Serial Boundary Scan

• JEDEC-standard 119-bump BGA package

• Pb-Free 119-bump BGA package available

GS815018/36A are implemented with high performance

technology and are packaged in a 119-bump BGA.

Family Overview

Mode Control

GS815018/36A are 18,874,368-bit (18Mb) high performance

SRAMs. This family of wide, low voltage HSTL I/O SRAMs

is designed to operate at the speeds needed to implement

economical high performance cache systems.

There are two mode control select pins (M1 and M2), which

allow the user to set the correct read protocol for the design.

The GS815018/36A support single clock Pipeline mode, which

directly affects the two mode control select pins. In order for

the part to fuction correctly, and as specified, M1 must be tied

to VSS and M2 must be tied to V or V

. This must be set

DDQ

at power-up and should not be changed during operation.

Sleep Mode

Low power (Sleep mode) is attained through the assertion (High)

of the ZZ signal, or by stopping the clock (CK). Memory data is

retained during Sleep mode.
