10 / 59 page 10 128Mb: x4, x8, x16 SDRAM Micron Technology, Inc., reserves the right to change products or specifications without notice. 128MSDRAM_E.p65 – Rev. E; Pub. 1/02 ©2001, Micron Technology, Inc. 128Mb: x4, x8, x16 SDRAM NOTE: 1. For full-page accesses: y = 2,048 (x4), y = 1,024 (x8), y = 512 (x16). 2. For a burst length of two, A1-A9, A11 (x4), A1-A9 (x8) or A1-A8 (x16) select the block-of-two burst; A0 selects the starting column within the block. 3. For a burst length of four, A2-A9, A11 (x4), A2-A9 (x8) or A2-A8 (x16) select the block-of-four burst; A0-A1 select the starting column within the block. 4. For a burst length of eight, A3-A9, A11 (x4), A3- A9 (x8) or A3-A8 (x16) select the block-of-eight burst; A0-A2 select the starting column within the block. 5. For a full-page burst, the full row is selected and A0-A9, A11 (x4), A0-A9 (x8) or A0-A8 (x16) select the starting column. 6. Whenever a boundary of the block is reached within a given sequence above, the following access wraps within the block. 7. For a burst length of one, A0-A9, A11 (x4), A0-A9 (x8) or A0-A8 (x16) select the unique column to be accessed, and mode register bit M3 is ignored.

Figure 1 Mode Register Definition Burst Type Accesses within a given burst may be programmed to be either sequential or interleaved; this is referred to as the burst type and is selected via bit M3. The ordering of accesses within a burst is determined by the burst length, the burst type and the starting col- umn address, as shown in Table 1. |
