Abstract

Computer/Microprocessor cores arc often designed to support several different types of memory devices, including EPROM/ROM, RAM and EEPROM. Com- plex processing elements typically support large mem- ory address spaces, requiring several 'banks' of memory devices to till the address space. In order to expand the available memory as the application software grows, the hardware typically supports several sizes of memory devices so that higher density devices can be used. As a result, the software needs to know what size device is installed so it can properly utilize the available memory space.
