Sleep mode is a low current, power-down mode in which the device is deselected and current is reduced to I
SB
2. The duration of
Sleep mode is dictated by the length of time the ZZ is in a high state. After entering Sleep mode, all inputs except ZZ become
disabled and all outputs go to High-Z The ZZ pin is an asynchronous, active high input that causes the device to enter Sleep mode.
When the ZZ pin is driven high, I
SB
2 is guaranteed after the time tZZI is met. Because ZZ is an asynchronous input, pending
operations or operations in progress may not be properly completed if ZZ is asserted. Therefore, Sleep mode must not be initiated
until valid pending operations are completed. Similarly, when exiting Sleep mode during tZZR, only a deselect or read commands
may be applied while the SRAM is recovering from Sleep mode.

Designing for Compatibility
The GSI NBT SRAMs offer users a configurable selection between Flow Through mode and Pipeline mode via the FT signal
found on Pin 14. Not all vendors offer this option, however most mark Pin 14 as V
DD
or V
DDQ
on pipelined parts and V
SS
on flow
through parts. GSI NBT SRAMs are fully compatible with these sockets.
Pin 66, a No Connect (NC) on GSI’s GS8160Z18/36 NBT SRAM, the Parity Error open drain output on GSI’s GS8161Z18/36
NBT SRAM, is often marked as a power pin on other vendor’s NBT compatible SRAMs. Specifically, it is marked V
DD
or V
DDQ
on pipelined parts and V
SS
on flow through parts. Users of GSI NBT devices who are not actually using the ByteSafe parity
feature may want to design the board site for the RAM with Pin 66 tied high through a 1k ohm resistor in Pipeline mode
applications or tied low in Flow Through mode applications in order to keep the option to use non-configurable devices open. By
using the pull-up resistor, rather than tying the pin to one of the power rails, users interested in upgrading to GSI’s ByteSafe NBT
SRAMs (GS8161Z18/36), featuring Parity Error detection and JTAG Boundary Scan, will be ready for connection to the active
low, open drain Parity Error output driver at Pin 66 on GSI’s TQFP ByteSafe RAMs.
