DUAL OPERATIONS AND MULTIPLE BANK ARCHITECTURE
The
Multiple
Bank
Architecture
of
the
M58LR128FT/B gives greater flexibility for soft-
ware developers to split the code and data spaces
within the memory array. The Dual Operations fea-
ture simplifies the software management of the de-
vice by allowing 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 operations
are possible in another bank with zero latency
(only one bank at a time is allowed to be in pro-
gram or erase mode).
If a read operation is required in a bank, which is
programming or erasing, the program or erase op-
eration can be suspended.
Also if the suspended operation was erase then a
program command can be issued to another
block, so the device can have one block in Erase
Suspend mode, one programming and other
banks in read mode.
Bus Read operations are allowed in another bank
between setup and confirm cycles of program or
erase operations.
By using a combination of these features, read op-
erations are possible at any moment in the
M58LR128FT/B device.
ble in other banks and in the same bank.
Table 12. Dual Operations Allowed In Other Banks
Table 13. 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.
