6507 General Description

The Galvantech 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 GVT71128E36 SRAM integrates 131,072x36 SRAM cells with advanced synchronous peripheral circuitry and a 2-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#),burst mode control (MODE), and sleep mode control (ZZ). he 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 onchip 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 and DQP1. BW2# controls DQ9-DQ16 and DQP2. BW3# controls DQ17-DQ24 and DQP3. BW4# controls DQ25-DQ32 and DQP4. BW1#,BW2# BW3#, and BW4# can be active only with BWE# being LOW. GW# being LOW causes all bytes to be written.

The GVT71128E36 operates from a +3.3V core power supply and all outputs operate on a +2.5V supply. All inputs and outputs are JEDEC standard JESD8-5 compatible. The device is ideally suited for 486, PentiumTM, 680x0, and PowerPCTM systems and for systems that are benefited from a wide synchronous data bus.
