1. Support copy-back program
- The copy-back program is configured to quickly and efficiently rewrite
data stored in one page within the array to another page within the
same array without utilizing an external memory. Since the time-con
suming sequently-reading and its re-loading cycles are removed, the
system performance is improved. The benefit is especially obvious
when a portion of a block is updated so that the rest of the block also
need to be copied to the newly assigned free block.

1. Explain how pointer operation works in detail.
2. For partial page programming into the copied page
- Once the copy-back Program is finished, any additional partial page
programming into the copied pages is prohibited before erase.
3. Renamed GND input (pin # 6) on behalf of SE (pin # 6)
- The SE input controls the access of the spare area. When SE is high,
the spare area is not accessible for reading or programming. SE is rec
ommended to be coupled to GND or Vcc and should not be toggled
during reading or programming.
=> Connect this input pin to GND or set to static low state unless the
sequential read mode excluding spare area is used.
4. Updated operation for tRST timing
- If reset command(FFh) is written at Ready state, the device goes into
Busy for maximum 5us.
1. In addition, explain WE function in pin description
- The WE must be held high when outputs are activated.
1.Powerup sequence is added
: Recovery time of minimum 1碌s is required before internal circuit gets
ready for any command sequences
