the write algorithm requirements for each bank. (For de-
tails, see Table 3 for software operation and Figures 8 for
timing waveforms. )
Product Identification Table
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 Table 3 for software operation and Figures 9 for
timing waveforms.)
Concurrent Read/Write State Table
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 manufac-
turer 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
