Method and apparatus for memory address decode in memory subsystems supporting a large number of memory devices
摘要:
One embodiment of the invention is a method for decoding a memory access address. A portion of the memory access address is compared to a plurality of boundary values, each of the plurality of boundary values representing an uppermost address for a group of memory devices, each of the memory devices in the group having the same configuration. A group number is generated that represents an addressed group that contains an addressed memory device that contains the memory access address. A device number is generated that represents the location of the addressed memory device within the addressed group. A device selection signal is generated responsive to the group number and the device number.
