Concurrent Read and Write Operations
The LE28DW3215AT-80 provides the unique benefit of being
able to read any bank, while simultaneously erasing, or
programming one other bank, This allows data alteration
code to be executed from one bank, while altering the data in
another bank. The next table lists all valid states.

Note: For the purposes of this table, write means to Block,
Sector, or Bank Erase, or Word Program as applicable
to the appropriate bank.
The device will ignore all SDP commands and toggling of
WE# when an Erase or Program operation is in progress.
Note, Product Identification entry commands use SDP;
therefore, this command will also be ignored while an Erase
or Program, operation is in progress.
Product Identification
The product identification mode identifies the device
manufacturer as SANYO and provides a code to identify each
bank. The manufacturer ID is the same for each bank;
however, each bank has a separate device ID. Each bank is
individually accessed using the applicable Bank Address and
a software command. Users may wish to use the device ID
operation to identify the write algorithm requirements for each
bank. (For details, see Table 3 for software operation and
Figure 8 for timing waveforms.)

Device ID codes are unique to each bank. Should a chip ID
be required, any of the bank IDs may be used as the chip ID.
While in the read software ID mode, no other operation is
allowed until after exiting these modes.
Product Identification Mode Exit
In order to return to the standard Read mode, the Product
Identification mode must be exited. Exit is accomplished by
issuing the Software ID exit command, which returns the
device to normal operation. This command may also be used
to reset the device to the Read mode after any inadvertent
transient condition that apparently causes the device to
behave abnormally, e. g., not read correctly. For details, (see
Table3 for software operation and Figures9 for timing
waveforms.)
