SDRAMs offer substantial advances in DRAM operating performance, including the abil-
ity to synchronously burst data at a high data rate with automatic column-address gen-
eration, the ability to interleave between internal banks in order to hide precharge time
and the capability to randomly change column addresses on each clock cycle during a
burst access.
