CY62256V Cypress Semiconductor, CY62256V Datasheet - Page 6

• Manufacturer Part Number: CY62256V
• Description: 32K x 8 Static RAM
• Manufacturer: Cypress Semiconductor

Switching Waveforms (continued)
Write Cycle No. 1 (WE Controlled)
Write Cycle No. 2 (CE Controlled)
Write Cycle No. 3 (WE Controlled, OE LOW)
Notes:
13. Data I/O is high impedance if OE = V
14. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
15. During this period, the I/Os are in output state and input signals should not be applied.
