Read Operation with Read Cahe

The device has a Read operation with Data Cache that enables the high speed read operation shown below.

When the block address changes, this sequence has to be started from the beginning.

For X8 :

If the 31h command is issued to the device, the data content of the next page is transferred to the Page Buffer

during serial data out from the Data Cache, and therefore the tR (Data transfer from memory cell to data

1 Normal read. Data is transferred from Page N to Data Cache through Page Buffer. During this time period, the device outputs Busy state

for tR max.

2 After the Ready/Busy returns to Ready, 31h command is issued and data is transferred to Data Cache from Page Buffer again. This data

transfer takes tDCBSYR1 max and the completion of this time period can be detected by Ready/Busy signal.

3 Data of Page N + 1 is transferred to Page Buffer from cell while the data of Page N in Data cache can be read out by

 clock

simultaneously.

4 The 31h command makes data of Page N + 1 transfer to Data Cache from Page Buffer after the completion of the transfer from cell to

Page Buffer. The device outputs Busy state for tDCBSYR1 max.

This Busy period depends on the combination of the internal data transfer time from cell to Page buffer and the serial data out time.

5 Data of Page N + 2 is transferred to Page Buffer from cell while the data of Page N + 1 in Data cache can be read out by

 clock

simultaneously.

6 The 3Fh command makes the data of Page N + 2 transfer to the Data Cache from the Page Buffer after the completion of the transfer

from cell to Page Buffer. The device outputs Busy state for tDCBSYR1 max. This Busy period depends on the combination of the internal

data transfer time from cell to Page buffer and the serial data out time.

7 Data of Page N + 2 in Data Cache can be read out, but since the 3Fh command does not transfer the data from the memory cell to Page

Buffer, the device can accept new command input immediately after the completion of serial data out.
