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
1.
One bus cycle is required to setup the Cache
Read command (the same as the standard
Read command)
2.
Four or Five (refer to Table 6. and Table 7.)
bus cycles are then required to input the 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. and
Table 9.). This allows the data to be output unin-
terrupted after the latency time (tBLBH1), see Fig-
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 inter-
nally 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 indi-
cates 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.
