WebJan 22, 2024 · However, these read-decoupled (RD) cells suffer the half-select disturbance while writing into a cell, hence they cannot support an efficient bit-interleaving structure. Some 8T, 9T, 10T, and 12T SRAM cells [11,12,13,14,15,16] employ cross-point (CP) access to eliminate the half 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). [1] Details [ edit]
