Abstract
A memory decoding system for a portable data terminal includes a memory controller, a memory storage, a first selection signal generator, and a second selection signal generator. The memory controller generates address signals and data signals. The memory storage is divided into a plurality of memory regions, and is controlled in such a manner as to write and read for the specified uses through the memory controller. The first selection signal generator outputs memory selecting signals to select one memory type of the memory storage. The second selection signal generator generates memory selecting signals to select another memory type of the memory storage. The portable terminal can be formed into a more compact type.
