Data, command and address are latched at the rising edge of WE#, Input Signal, disables Flash array program and erase operations. This hardware interface creates a low-pin-count device with a standard pinout that is the same from one density to another, allowing future upgrades to higher densities with-out board redesign. A brief description of the signals is given in Table 4 with a schematic form in Figure 4. Many of these devices will also drive new use cases, potentially generating more service revenue as outlined in the diagram: eMMC 5.1 can still meet the demand for some devices migrating initially from 4G to 5G. Unlike many protocols the NAND interface has no framing of data transfers with which to synchronize transfers. This same protocol is used by ASRAM devices as well. NAND and NVMe aren’t in competition with each other.
