Dual operations and multiple bank architecture
The Multiple Bank Architecture of the M58WR064HU/L provides flexibility for software
developers 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 programming 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 Program or Erase mode). If a Read operation is required in a bank which is
programming or erasing, the Program or Erase operation 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. The combination of these features means
that read operations are possible at any moment.
Dual operations between the Parameter Bank and the CFI, OTP or Electronic Signature
memory space, are not allowed. Table 14: Dual operation limitations shows which dual
operations are allowed between the CFI, OTP, Electronic Signature locations and the
same bank. Note that only the commonly used commands are represented in these tables.
For a complete list of possible commands refer to Appendix D: Command interface state
