PROBLEM TO BE SOLVED: To express the function of a line memory with a kind of bit line. SOLUTION: Since word lines WLj-1 , WLj are activated in this order, read- out is performed already before new write-in is performed to memory cells MCj-1 ,i , MCj ,i . That is, since a write-in process is executed to the same memory cell after a read-out process, delay operation is realized similarly to a usual technique. Moreover, since operation of a try state buffer 11 and a D latch 13 are controlled according to the read-out process and write-in process, a write-in bit line is shared with a read-out bit line. |
