The function of the Data Output register can be controlled by the user via the FT mode pin/bump (Pin 14 in the TQFP, bump 1F in the FPBGA). 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.
DCD Pipelined Reads
The GS820E32A is a DCD (Dual Cycle Deselect) pipelined synchronous SRAM. SCD (Single Cycle Deselect) versions are also available. DCD SRAMs pipeline disable mands to the same degree as read mands. DCD RAMs hold the deselect mand for one full cycle and then begin turning off their outputs just after the second rising edge of clock.
Byte Write and Global Write
Byte write operation is performed by using byte write enable (BW) input bined with one or more individual byte write...
