Status Register bits
Read status enhanced
In NAND Flash devices with multiplane architecture, it is possible to independently read the
Status Register of a single plane using the Read Status Enhanced command. If the Error bit
of the Status Register, SR0, reports an error during or after a multiplane operation, the Read
Status Enhanced command is used to know which of the two planes contains the page that
failed the operation. Three address cycles are required to address the selected block and
page (A18-0).
The output of the Read Status Enhanced command has the same coding as the Read
Status command. See
enhanced waveform.
Read EDC Status Register
The devices contain an EDC Status Register, which provides information on the errors that
occurred during the read cycles of the copy back and multiplane copy back operations. In
the case of multiplane copy back program, it is not possible to distinguish which of the two
read operations caused the error.
The EDCS Status Register is read by issuing the Read EDC Status Register command.
After issuing the Read EDC Status Register command, a read cycle outputs the content of
the EDC Status Register to the I/O pins on the falling edge of Chip Enable or Read Enable
signals, whichever occurs last. The operation is similar to Read Status Register command.
