to high impedance, independently from the Output Enable or Write Enable inputs. If Chip
Enable switches to V
mode when finished.
Automatic Standby
Automatic standby provides a low power consumption state during Read mode. Following a
read operation, the device enters automatic standby after 150 ns of bus inactivity even if
Chip Enable is Low, V
will still output data if a bus read operation is in progress.
Reset
During Reset mode when Output Enable is Low, V
outputs are high impedance. The memory is in Reset mode when Reset is at V
consumption is reduced to the standby level, independently from the Chip Enable, Output
Enable or Write Enable inputs. If Reset is pulled to V
operation is aborted and the memory content is no longer valid.
