Read Status Register
Read Status Enhanced — S34ML02G1 and S34ML04G1
The Status Register is used to retrieve the status value for the last operation issued. After writing 70h
command to the command register, a read cycle outputs the content of the Status Register to the I/O pins on
the falling edge of CE# or RE#, whichever occurs last. This two-line control allows the system to poll the
progress of each device in multiple memory connections even when R/B# pins are common-wired. Refer to
Section 3.5 on page 29
on page 55
If the Read Status Register command is issued during multiplane operations then Status Register polling will
return the combined status value related to the outcome of the operation in the two planes according to the
following table:
In other words, the Status Register is dynamic; the user is not required to toggle RE# / CE# to update it.
The command register remains in Status Read mode until further commands are issued. Therefore, if the
Status Register is read during a random read cycle, the read command (00h) should be given before starting
read cycles.
Note: The Read Status Register command shall not be used for concurrent operations in multi-die stack
configurations (single CE#). “Read Status Enhanced” shall be used instead.
Read Status Enhanced is an additional feature used to retrieve the status value for a previous operation in
the case of multiplane operations in the same die.
