Memory IC FAQ

How does the device manage power consumption during idle states?

The device enters a standby mode when deselected, reducing power consumption by more than 99%. Outputs enter a high-impedance state to further minimize leakage currents.

What is the mechanism for controlling individual bytes?

Independent Byte High Enable (BHE) and Byte Low Enable (BLE) signals allow selective writing and reading of the upper or lower 8 bits of the 16-bit word.
