Multi-Plane Copy-Back Program
Multi-Plane Copy-Back Program is an extension of one page Copy-Back Program into four plane operation. Since the device is
equipped with four memory planes, activating the four sets of 528 bytes(x8 device) or 264words(x16 device)page registers enables a
simultaneous Multi-Plane Copy-Back programming of four pages. Partial activation of four planes is also permitted.
First, normal read operation with the "00h"command and address of the source page moves the whole 528 byte data into internal
page buffers. Any further read operation for transferring the addressed pages to the corresponding page register must be executed
with "03h" command instead of "00h" command. Any plane may be selected without regard to "00h" or "03h". Up to four planes may
be addressed. Data moved into the internal page registers are loaded into the destination plane addresses. After the input of com-
mand sequences for reading the source pages, the same procedure as Multi-Plane Page programming except for a replacement
address command with "8Ah" is executed. Since no programming process is involved during data loading at the destination plane
address , R/B remains in Busy state for a short period of time(tDBSY). Read Status command (standard 70h or alternate 71h) may be
issued to find out when the device returns to Ready state by polling the Ready/Busy status bit(I/O 6). After inputting data for the last
plane, actual True Page Program (10h) instead of dummy Page Program command (11h) must be followed to start the programming
process. The operation of R/B and Read Status is the same as that of Page Program. Since maximum four pages are programmed
simultaneously, pass/fail status is available for each page when the program operation completes. No pointer operation is supported
with Multi-Plane Copy-Back Program. Once the Multi-Plane Copy-Back Program is finished, any additional partial page pro-
gramming into the copied pages is prohibited before erase once the Multi-Plane Copy-Back Program is finished.
