Semiconductor memory device performing last in-first out operation and the method for controlling the same |
摘要 |
A LIFO device includes a plurality of memory circuits (1), a write address pointer (2) and a read-out address pointer (3). The write address pointer (2) selects the memory circuit (1) in which data are to be written, while the read-out address pointer (3) selects the memory circuit (1) from which data are to be read out. Each of the write address pointer (2) and the read-out address pointer (3) alternately and repeatedly performs the count-up operation for selecting the memory circuits in a predetermined sequence and the count-down operation of selecting the memory circuits in a sequence which is the reverse of the predetermined sequence. Control is also so made that the selection by the read-out address pointer (3) precedes the selection by the write address pointer (2).
