DESCRIPTION
The WEDC SyncBurst - SRAM family employs high-speed, low-
power CMOS designs that are fabricated using an advanced
CMOS process. WEDC’s 16Mb SyncBurst SRAMs integrate two
512K x 18 SRAMs into a single BGA package to provide 512K x
36 configuration. All synchronous inputs pass through registers
controlled by a positive - edge-triggered single-clock input (CLK).
The synchronous inputs include all addresses, all data inputs,
active LOW chip enable (CE), burst control inputs (ADSC, ADSP,
ADV), byte write enables (BW0-3) and global write (GW). Asyn-
chronous inputs include the output enable (OE), clock (CLK) and
snooze enable (ZZ). There is also a burst mode input (MODE) that
selects between interleaved and linear burst modes. Write Cycles
can be from one to four bytes wide, as controlled by the write
control inputs. Burst operation can be initiated with either address
status processor (ADSP) or address status controller (ADSC)
inputs. Subsequent burst addresses can be internally generated
as controlled by the burst advance input (ADV).
