For full-page accesses y = 2048 x4 y = 1024 x8 y = 512 x16 . For BL = 2, A11 x4 x8 or x16 select the block-of-two burst A0
selects the starting column within the block. For BL = 4, A11 x4 x8 or x16 select the block-of-four burst;
select the starting column within the block. For BL = 8, A11 x4 x8 or x16 select the block-of-eight burst;
select the starting column within the block. For a full-page burst, the full row is selected and A11 x4 x8 or
x16 select the starting column. Whenever a boundary of the block is reached within a given sequence above, the fol-
lowing access wraps within the block. For BL = 1, A11 x4 x8 or x16 select the unique column to be
accessed, and mode register bit M3 is ignored.

CAS Latency

The CAS latency CL is the delay, in clock cycles, between the registration of a READ command and the availability of the output data. The latency can be set to two or three clocks.

If a READ command is registered at clock edge n, and the latency is m clocks, the data will be available by clock edge n + m. The DQ start driving as a result of the clock edge one cycle earlier n + m - 1 , and provided that the relevant access times are met, the data is valid by clock edge n + m. For example, assuming that the clock cycle time is such that all relevant access times are met, if a READ command is registered at T0 and the latency is programmed to two clocks, the DQ start driving after T1 and the data is valid by T2.

Reserved states should not be used as unknown operation or incompatibility with future versions may result.
