READ PAGE TWO-PLANE 00h-00h-30h

The READ PAGE TWO-PLANE (00h-00h-30h) operation is similar to the PAGE READ
(00h-30h) operation. It transfers two pages of data from the NAND Flash array to the da-
ta registers. Each page must be from a different plane on the same die.
To enter the READ PAGE TWO-PLANE mode, write the 00h command to the command
register, and then write five address cycles for plane 0 (BA6 = 0). Next, write the 00h
command to the command register, and five address cycles for plane 1 (BA6 = 1). Final-
ly, issue the 30h command. The first-plane and second-plane addresses must meet the
two-plane addressing requirements, and, in addition, they must have identical column
addresses.
After the 30h command is written, page data is transferred from both planes to their re-
spective data registers in
are complete, R/B# goes HIGH. To read out the data from the plane 0 data register,
pulse RE# repeatedly. After the data cycle from the plane 0 address completes, issue a
RANDOM DATA READ TWO-PLANE (06h-E0h) command to select the plane 1 address,
then repeatedly pulse RE# to read out the data from the plane 1 data register.
Alternatively, the READ STATUS (70h) command can monitor data transfers. When the
transfers are complete, status register bit 6 is set to 1. To read data from the first of the
two planes, the user must first issue the RANDOM DATA READ TWO-PLANE (06h-E0h)
command and pulse RE# repeatedly.
When the data cycle is complete, issue a RANDOM DATA READ TWO-PLANE (06h-E0h)
command to select the other plane. To output the data beginning at the specified col-
umn address, pulse RE# repeatedly.
Use of the READ STATUS ENHANCED (78h) command is prohibited during and follow-
ing a PAGE READ TWO-PLANE operation.
