Abstract

PURPOSE:To make access to a memory without sensing a memory constitution by recognizing the constitution of the memory previously to an ordinary memory access and storing this result in a memory constitution register. CONSTITUTION:Initially, a memory constitution recognizing mode is instructed to a constitution recognition flag register 105. Consequently, the constitution recognizing mode is obtained, a capacity discriminating circuit 106 has the data input 117 of a memory constitution information register 104 to discriminate the memory constitution. A memory package selecting circuit 107 has the output signal 115 of an address decoder 114 and the output signal 124 of the circuit 106 as the input and outputs a RAS signal 119 corresponding to respective connectors 102a-d. A RAS signal forming circuits 108a-d select the output signal 115 of an address decoder 113 by the data 118 of the register 105 to form a RAS signal 120 to memory package 103a-d. Thereby, successively address are allocated to the arbitrary combination of the connectors 102a-d and the packages 103a-d.
