Holding the FT mode pin/bump low, places the RAM in Flow through mode, causing output data to bypass the Data Output Register. Holding FT high places the RAM in Pipelined Mode, activating the rising edge triggered Data Output Register. Pipelined Reads The GS820H32A is an SCD (Single Cycle Deselect) pipelined synchronous SRAM. DCD (Dual Cycle Deselect) versions are also available. SCD SRAMs pipeline deselect commands one stage less than read commands. SCD RAMs begin turning off their outputs immediately after the deselect command has been captured in the input registers. Byte Write and Global Write Byte write operation is performed by using byte write enable (BW) input combined with one or more individual byte write signals (Bx). In addition, Global Write (GW) is available for writing all bytes at one time, regardless of the Byte Write control inputs. 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. Functional Description Applications The GS820H32A is a 2,097,152 bit high performance synchronous SRAM with a 2 bit burst address counter. Although of a type originally developed for Level 2 Cache applications supporting high performance CPU’s, the device now finds application in synchronous SRAM applications ranging from DSP main store to networking chip set support. Core and Interface Voltages The GS820H32A operates on a 3.3V power supply and all inputs/ outputs are 3.3V and 2.5V compatible. Separate output power (VDDQ) pins are used to de-couple output noise from the internal circuit. Controls Addresses, data I/O’s, chip enables (E1, E2, E3), address burst control inputs (ADSP, ADSC, ADV ) and write control inputs (Bx, BW, GW) are synchronous and are controlled by a positive edge triggered clock input (CK). Output enable (G) and power down control (ZZ) are asynchronous inputs. Burst cycles can be initiated with either ADSP or ADSC inputs. In Burst mode, subsequent burst addresses are generated internally and are controlled by ADV. The burst address counter may be configured to count in either linear or interleave order with the Linear Burst Order (LBO) input. The Burst function need not be used. New addresses can be loaded on every cycle with no degradation of chip performance. Rev: 1.04 3/2000 1/23 © 2000, Giga Semiconductor, Inc. E Specifications cited are subject to change without notice.

Dummy read cycles waste performance but their use usually assures there will be no bus contention in transitions from reads to writes or between banks of RAMs. DCD SRAMs do not waste bandwidth on dummy cycles and are logically simpler to manage in a multiple bank application (wait states need not be inserted at bank address boundary crossings) but greater care must be exercised to avoid excessive bus contention.
