Device Architecture
Read Operation
Read operations are designed to read data from the FB Array, Page Buffer, Block Buffer, or status
registers. Read operations support a normal read and a read-ahead mode (done by asserting
READNEXT). Also, the timing for Read operations is dependent on the setting of PIPE.
The following diagrams illustrate representative timing for Non-Pipe Mode (Figure

reads of the flash memory block interface.
