IS42S16100C1
Read Cycle (Full Page) Interruption Using
the Burst Stop Command
The IS42S16100C1 can output data continuously from
the burst start address (a) to location a+255 during a
read cycle in which the burst length is set to full page.
The IS42S16100C1 repeats the operation starting at
the 256th cycle with the data output returning to location
(a) and continuing with a+1, a+2, a+3, etc. A burst stop
command must be executed to terminate this cycle. A
precharge command must be executed within the ACT
to PRE command period (t
stop command.
