<p>PROBLEM TO BE SOLVED: To eliminate the need for a plurality of buffers, when they are required in a repeated use of a plurality of instructions such as in a loop instruction in a semiconductor device and the range of repetition includes boundaries of respectively independent buffers in an instruction buffer. SOLUTION: By dividing sub-sense amplifier circuits 307 connected to sub-bit line pairs S0BL selected by the same word line DWL into two or more groups, reading information by sub-bit line pairs in different groups to main bit line pairs MBL, then reading the information as it is by an additional sense amplifier circuit 302, a plurality of buffers are made unnecessary even when an instruction repeated in a loop instruction straddles over a register boundary and the information is made to be copied to a single buffer.</p> |
