The GHX-308A contains all system memories, which composed of 128Kbyte of ROM and 32Kbyte of RAM. The RAM is
subdivided so that part is used as CPU working area and part is used for customer database. The customer database
memory is protected from loss by a long-life lithium battery. The system generic memory(ROM) is mounted in the IC
socket on the MBU. This allows easy access for removal of system software when upgrading software feature package.
