WebNote that the address lines on the address bus of the CPU will be "wired" to the row address, memory bank, column address and chip select. The address lines can be wired arbitrarily, so that a section of RAM associated with a memory bank may appear to the CPU either to be contiguous or interleaved with other memory banks. WebIn low–order interleaving, consecutive addresses in the memory will be found in different memory banks. Consider a 64–word memory that is 4–way interleaved. This means that there are four memory banks, each holding 16 words. If this memory is also low–order interleaved, we have the following allocation of words to banks.

WebMay 23, 2024 · Figure 11 of the Reference Manual shows this type of connection. However, the LS1043A reference design uses two chip selects for its one and only rank. CS0 … WebA memory rank is a set of DRAM chips connected to the same chip select, which are therefore accessed simultaneously. In practice all DRAM chips share all of the other command and control signals, and only the chip select pins for each rank are separate (the data pins are shared across ranks).
