WebDIMMs feature two 40-bit (32 bits plus ECC) independent channels. When combined with a new default burst length of 16 (BL16) in the DDR5 component, this allows a single burst to access 64B of data (the typical CPU cache line size) using only one of the independent channels, or only half of the DIMM.

Webthe precharge state. The mode register is divided into various fields depending on functionality. Burst length is defined by A0 ~ A2 with options of 4 and 8 bit burst lengths. The burst length decodes are compatible with DDR SDRAM. Burst address sequence type is defined by A3, CAS latency is defined by A4 ~ A6.

First part: No, what you have described is in fact "fast page mode" and not burst mode. This mode only applies to old-fashioned non-synchronous DRAMs (and not all of them supported it), which don't have internal banks, and not to any kind of modern SDRAM.
