DUAL OPERATIONS AND MULTIPLE BANK ARCHITECTURE
The
Multiple
Bank
Architecture
of
the
M58WR128E provides flexibility for software de-
velopers by allowing code and data to be split with
4Mbit granularity. The Dual Operations feature
simplifies the software management of the device
and allows code to be executed from one bank
while another bank is being programmed or
erased.
The Dual operations feature means that while pro-
gramming or erasing in one bank, Read opera-
tions are possible in another bank with zero
latency (only one bank at a time is allowed to be in
Program or Erase mode). If a Read operation is re-
quired in a bank which is programming or erasing,
the Program or Erase operation can be suspend-
ed. Also if the suspended operation was Erase
then a Program command can be issued to anoth-
er block, so the device can have one block in
Erase Suspend mode, one programming and oth-
er banks in Read mode. Bus Read operations are
allowed in another bank between setup and con-
firm cycles of program or erase operations. The
combination of these features means that read op-
erations are possible at any moment.
ble in other banks and in the same bank. For a
complete list of possible commands refer to Ap-
pendix D, Command Interface State Tables.
Table 11. Dual Operations Allowed In Other Banks
Table 12. Dual Operations Allowed In Same Bank
Note: 1. Not allowed in the Block or Word that is being erased or programmed.
2. The Read Array command is accepted but the data output is not guaranteed until the Program or Erase has completed.
