Clock Truth Table
Notes:
1. “1” = input “high”; “0” = input “low”; “X” = input “don’t care”.
2. “***” indicates that the input requirement or output state is determined by the previous operation.
3. DQs are tri-stated in response to Write and Deselect commands, one cycle after the command is sampled.
Sleep (Power Down) Mode
Sleep (power down) mode is provided through the asynchronous input signal ZZ. When ZZ is asserted (high), the output
drivers are disabled and the SRAM begins to draw standby current. Contents of the memory array are preserved. An enable
time (tZZE) must be met before the SRAM is guaranteed to be in sleep mode, and a recovery time (tZZR) must be met before
the SRAM can resume normal operation.
Programmable Impedance Output Drivers
These devices have programmable impedance output drivers. The output impedance is controlled by an external resistor RQ
connected between the SRAM’s ZQ pin and VSS, and is equal to one-fifth the value of this resistor, nominally. See the DC
Electrical Characteristics section for further information.
Output Driver Impedance Power-Up Requirements
Output driver impedance will reach the programmed value within 8192 cycles after power-up. Consequently, it is recom-
mended that Read operations not be initiated until after the initial 8192 cycles have elapsed.
Output Driver Impedance Updates
Output driver impedance is updated during Write and Deselect operations when the output driver is disabled.
Power-Up Sequence
For reliability purposes, Sony recommends that power supplies power up in the following sequence: VSS, VDD, VDDQ, VREF,
and Inputs. VDDQ should never exceed VDD. If this power supply sequence cannot be met, a large bypass diode may be re-
quired between VDD and VDDQ. Please contact Sony Memory Application Department for further information.
