Full-speed random READ accesses (Burst Length = 2, 4, 8 or 16) within a page (or pages) can be performed as shown in
Figure
Note: This timing diagram is only applicable for the consecutive READ from the same die.
2.4.5.1
Data from any READ burst may be truncated using the BURST TERMINATE command (see
Precharge was not activated. The BURST TERMINATE latency is equal to the CAS latency, i.e. the BURST TERMINATE
command should be issued x clock cycles after the READ command, where x equals the number of desired data element pairs.
