    摘要: An address decoding circuit for a functional block comprises branch portions serially connected with each other, in which a selecting signal is outputted on one of two output portions in accordance with the first bit information of an address signal when a selecting signal is applied to the first stage branch portion. The second stage output portion, to which the selecting signal is applied, outputs a selecting signal on one of two output portions in response to the second bit information of the address signal, in accordance with the selecting signal. Thereafter, each branch portion of the third to last stages outputs a selecting signal on one of two output portions in response to respective contents of the third bit to last bit of the address signal in accordance with the selecting signal applied from the preceding stage. By this selecting signal, a memory cell as a functional block portion is selected and is activated.

    摘要: A semiconductor memory includes a memory cell array having a plurality of bit lines and a plurality of word lines arranged intersecting with the bit lines. A plurality of memory cells are arranged at intersections of the bit lines and the word lines, respectively. Word line selecting circuitry selects one of the word lines responsive to a row address and reads out to each of the bit lines information stored in the memory cell associated with the selected word line. A plurality of sense amplifiers are associated with corresponding rows of the memory for detecting and amplifying the information stored in respective memory cells. A first column selector circuit selects the sense amplifiers corresponding to a column address when the column address is applied and reads information held in the sense amplifier. Blocks are formed by dividing the memory cell array into groups of bit lines, each of the groups comprising a predetermined number of bit lines with block information transferred simultaneously from corresponding ones of the groups of bit lines of a selected block when the column address corresponding to the selected block is applied. Data registers hold information of an associated block. A second column selector reads data corresponding to the column address from the data register when the column address is applied.
