Cache Read
The Cache Read operation is used to improve the read throughput by reading data using
the Cache Register. As soon as the user starts to read one page, the device automatically
loads the next page into the Cache Register.
An Cache Read operation consists of three steps (see Table 10: Commands):
1.
One bus cycle is required to setup the Cache Read command (the same as the
standard Read command)
2.
Start Address
3.
One bus cycle is required to issue the Cache Read confirm command to start the P/E/R
Controller.
The Start Address must be at the beginning of a page (Column Address = 00h, see Table 8
see Figure 9
The Ready/Busy signal can be used to monitor the start of the operation. During the latency
period the Ready/Busy signal goes Low, after this the Ready/Busy signal goes High, even if
the device is internally downloading page n+1.
Once the Cache Read operation has started, the Status Register can be read using the
Read Status Register command.
During the operation, SR5 can be read, to find out whether the internal reading is ongoing
(SR5 = ‘0’), or has completed (SR5 = ‘1’), while SR6 indicates whether the Cache Register
is ready to download new data.
To exit the Cache Read operation an Exit Cache Read command must be issued (see
Table 10).
If the Exit Cache Read command is issued while the device is internally reading page n+1,
page n will still be output, but not page n+1.
