NORMAL-READ TRANSFER
(refer to Figure 7)
address bits (A0– A8) are latched at the falling edge of CAS\ to
select one of the SAM’s 512 available tap points where the
serial data is read out.

early-load read transfer, real-time or midline-load read transfer,
and late-load read transfer. Each of these offers the flexibility of
controlling the TRG\ trailing edge in the read-transfer cycle
(see Figure 7).
A normal-read transfer can be performed in three ways:
