• Manufacturer Part Number: GS880E36BT-250IV
• Description: 512K x 18, 256K x 32, 256K x 36 9Mb Sync Burst SRAMs
• Manufacturer: GSI [GSI Technology]

Sleep Mode
During normal operation, ZZ must be pulled low, either by the user or by its internal pull down resistor. When ZZ is pulled high,
the SRAM will enter a Power Sleep mode after 2 cycles. At this time, internal state of the SRAM is preserved. When ZZ returns to
low, the SRAM operates normally after ZZ recovery time.
