128K x 32 Synchronous-Pipelined RAM
3901 North First Street
Functional Description
The Cypress Synchronous Burst SRAM family employs
high-speed, low-power CMOS designs using advanced
triple-layer polysilicon, double-layer metal technology. Each
memory cell consists of four transistors and two high valued
resistors.
The CY7C1340A/GVT71128C32 SRAM integrates 131,072 ×
32 SRAM cells with advanced synchronous peripheral circuitry
and a two-bit counter for internal burst operation. All
synchronous inputs are gated by registers controlled by a
positive-edge-triggered Clock Input (CLK). The synchronous
inputs include all addresses, all data inputs, address-pipelining
chip enable (CE), depth-expansion Chip Enables (CE2 and
CE2), Burst Control Inputs (ADSC, ADSP, and ADV), Write
Enables (BW1, BW2, BW3, BW4, and BWE), and Global Write
(GW).
Asynchronous inputs include the Output Enable (OE) and
Burst Mode Control (MODE). The data outputs (Q), enabled
by OE, are also asynchronous.
Addresses and chip enables are registered with either
Address Status Processor (ADSP) or Address Status
Controller (ADSC) input pins. Subsequent burst addresses
can be internally generated as controlled by the Burst Advance
Pin (ADV).
Address, data inputs, and Write controls are registered on-chip
to initiate self-timed Write cycle. Write cycles can be one to
four bytes wide as controlled by the Write control inputs.
Individual byte Write allows individual byte to be written. BW1
controls DQ1–DQ8. BW2 controls DQ9–DQ16. BW3 controls
DQ17–DQ24. BW4 controls DQ25–DQ32. BW1, BW2, BW3,
and BW4 can be active only with BWE being LOW. GW being
LOW causes all bytes to be written. This device also incorpo-
rates pipelined enable circuit for easy depth expansion without
penalizing system performance.
The CY7C1340A/GVT71128C32 operates from a +3.3V
power supply. All inputs and outputs are TTL-compatible. The
device is ideally suited for 486, Pentium®, 680 × 0, and
PowerPC™ systems and for systems that benefit from a wide
synchronous data bus.
