Automatic Standby
Automatic Standby provides a low power consumption state during Read mode. Following a
read operation, the device enters Automatic Standby after 150ns 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operation is aborted and the memory content is no longer valid.
