contention. This device can be read or reprogrammed
using a single 2.7V power supply, making it ideally suited
for in-system programming.
The device powers on in the read mode. Command
sequences are used to place the device in other operation
modes such as program and erase. The device has the
capability to protect the data in any sector. Once the data
protection for a given sector is enabled, the data in that
sector cannot be changed using input levels between
ground and V
The device is segmented into two memory planes. Reads
from memory plane B may be performed even while

program or erase functions are being executed in memory
plane A and vice versa. This operation allows improved
system performance by not requiring the system to wait for
a program or erase operation to complete before a read is
performed. To further increase the flexibility of the device, it
contains an Erase Suspend feature. This feature will put
the erase on hold for any amount of time and let the user
read data from or program data to any of the remaining
sectors within the same memory plane. There is no reason
to suspend the erase operation if the data to be read is in
the other memory plane. The end of a program or an erase
cycle is detected by the Ready/Busy pin, Data Polling or by
the toggle bit.
