Abstract
PURPOSE: To simplify the circuit constitution of the 2-dimensional memory device by using the memory element which can give the simultaneous access to the S bit per word.
CONSTITUTION: Memory elements 60 composed of each word S bit of N units in all plus the R words are arrayed in the 2-dimensional way to enable the I-bit (I≥S) simultaneous access. Then the selection signal is supplied to element 60 from X address register 10, Y address register 20 via line decoder 30, row decoder 40 and intra-element address register 50 each. And if access mode 1 is designated to access mode line 3, the simultaneous and parallel input/output is given to the data of I-bit. While the J-bit data featuring S≤J≤I is supplied and delivered with designation of access mode 2. Also with installation of the j-bit serial-parallel register to recorder 40, the simultaneous and parallel input/output is possible for the data of J×J bits. Thus the circuit constitution can be simplified for the 2-dimensional memory device.
