Copy back program
The copy back program operation is used to copy the data stored in one page and
reprogram it in another page.
The copy back program operation does not require external memory and so the operation is
faster and more efficient because the reading and loading cycles are not required. The
operation is particularly useful when a portion of a block is updated and the rest of the block
needs to be copied to the newly assigned block.
If the copy back program operation fails, an error is signalled by the pass/fail status.
However, if copy back operations are accumulated over time, a bit error due to charge loss is
not checked by an external error detection/correction scheme. For this reason it is
recommended to use a 2-bit error correction in a copy back operation.
The copy back program operation requires four steps:
1.
The first step reads the source page. The operation copies all 1056 words/ 2112 bytes
from the page into the data buffer. It requires:
–
one bus write cycle to setup the command
–
–
one bus write cycle to issue the confirm command code
2.
When the device returns to the ready state (Ready/Busy High), the user may read the
contents of the source page by toggling R. In this case, random data output is also
allowed. To proceed with the copy back of the page into the target location, the user will
issue 85h followed by 4 bus cycles to input the target page address (see Table 6 and
3.
Then the confirm command is issued to start the P/E/R controller.
For an example of the copy back program operation, refer to Figure 12, while Figure 13
shows an example of Copy Back Program with Random Data Input.
A data input cycle to modify a portion or a multiple distant portion of the source page, is
shown in Figure 13.
