Methods and apparatus that allow for dynamic selection of page size or number of banks in a dynamic random access memory device. A number of available banks of the memory device may be selectively increased for systems application which optimally require more banks while keeping the number of devices in the system relatively small. Such devices may then also be incorporated in systems, for example, a personal computer, where the number of memory devices used is high, but the number of banks required in those devices is small. In an embodiment, a sub-page activation apparatus and protocol is used to reduce the memory device page size and allow for reduced power consumption. Resources are dedicated for individual precharging and sensing of each subpage.
