As described above, certain modes of operation, such as the Fast Zero mode and the ECS mode, may facilitate sequential access to individual cells of a memory array. To facilitate this functionality, a command controller may be provided, including one or more individual controllers to control the address sequencing when a particular mode entry command (e.g., Fast Zero or ECS) is received. In order to generate internal addresses to be accessed sequentially, one or more counters may also be provided. Advantageously, the counters may be shared such that they can be used in any mode of operation that may require address sequencing of all or large portions of the memory array, such as the Fast Zero mode or the ECS mode.
