Abstract
A method and apparatus for providing memory system status signals in an information processing system is disclosed. The memory system includes a bus which couples a memory unit, for storing information units, to a memory control unit. The memory control unit provides addresses to the memory unit. The memory unit stores or retrieves information units from memory locations corresponding to the provided address. The memory unit provides a status signal to the memory control unit indicating a status of the memory access being provided. The status signals provided by the memory unit indicate whether the provided memory address is within the range of addresses stored in the memory unit, the access speed of the memory devices in the memory unit, or the type of memory devices in the memory unit.
