The device is designed to offer protection from any involuntary program/erase during power-transitions.
An internal voltage detector disables all functions whenever Vcc is below POR level, about 1.3V. It is recommended that the RP pin,
which provides hardware protection, should be kept at VIL before power-down.
3.6 Load Operation
See Timing Diagram 6.8
The Load operation is initiated by setting up the start address from which the data is to be loaded. The Load command is issued in
order to initiate the load.
During a Load operation, the device:
-Transfers the data from NAND Flash array into the BufferRAM
-ECC is checked and any detected and corrected error is reported in the status response as well as
any unrecoverable error.
Once the BufferRAM has been filled, an interrupt is issued to the host so that the contents of the BufferRAM can be read. The read
from the BufferRAM can be an asynchronous read mode or synchronous read mode. The status information related to load operation
can be checked by the host if required.
The device has a dual data buffer memory architecture (DataRAM0, DataRAM1), each 2KB in size. Each DataRAM buffer has 4
Sectors. The device is capable of independent and simultaneous data-read operation from one data buffer and data-load operation to
the other data buffer. Refer to the information for more details in section 3.12.1, "Read-While-Load Operation".
