PURPOSE:To decrease the hard quantity of a memory peripheral circuit for a 2- dimensional memory which is used in a nipple mode, by having the common alignment of bits between the horizontal and vertical image secondary array data. CONSTITUTION:A bit alignment circuit consists of a 4-1 selection circuit 18, a 0-3 bit left circular shift circuit 19, a shift register 20 and a 0-3 bit left circular shift circuit 21. The bit alignment circuit can pass through a processing path equal to a vertical reading data by converting artificially a horizontal reading data into a series type data equal to the vertical reading data. |
