Intel StrataFlash Wireless Memory (L18)
Order Number: 251902, Revision: 009
Datasheet
To read data from a block in other partition and the other partition already in read array mode, a
new block address must be issued. However, if the other partition is
not
already in read array mode,
issuing a read array command will cause the buffered program operation to abort and a command
sequence error would be posted in the Status Register. See
Figure 41, “Buffer Program Flowchart”
on page 87
for more details.
Note:
Simultaneous read-while-Buffered EFP is not supported.
14.3
Simultaneous Operation Restrictions
Since the Intel StrataFlash Wireless Memory (L18) supports simultaneous read from one
partition while programming or erasing in another partition, certain features like the Protection
Registers and CFI Query data have special requirements with respect to simultaneous operation
capability. (
Table 15
provides details on restrictions during simultaneous operations.)

Write/Erase
While programming or erasing in a main partition, the Protection Register or CFI
data may be read from any other partition.
Reading the parameter partition array data is not allowed if the Protection Register
or Query data is being read from addresses within the parameter partition.
While programming or erasing in a main partition, read operations are allowed in the
parameter partition.
Accessing the Protection Registers or CFI data from parameter partition addresses
is not allowed when reading array data from the parameter partition.
While programming or erasing in a main partition, read operations are allowed in the
parameter partition.
Accessing the Protection Registers or CFI data in a partition that is
different
from the
one being programed/erased, and also
different
from the parameter partition is
allowed.
While programming the Protection Register, reads are only allowed in the other
main partitions.
Access to array data in the parameter partition is not allowed. Programming of the
Protection Register can only occur in the parameter partition, which means this
partition is in Read Status.
While programming or erasing the parameter partition, reads of the Protection
Registers or CFI data are not allowed in
any
partition.
Reads in partitions other than the parameter partition are supported.
