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  
DD  
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.
