Note:
Reset (RP)
The Reset input provides a hardware reset of the memory. When Reset is at V
memory is in reset mode: the outputs are high impedance and the current consumption is
minimized. After Reset all blocks are in the locked state. When Reset is at V
in normal operation. Exiting reset mode the device enters read array mode, but a negative
transition of Chip Enable or a change of the address is required to ensure valid data outputs.
