Abstract
An image data memory with a 2-bank (bank A and bank B) structure is disclosed. The bank A stores only even field data, whereas the bank B stores only odd field data, and a peripheral circuit composed of elements such as row decoders and column decoders is provided in such a manner that each bank can be accessed independently of the other. One of the banks A and B is precharged while the other bank is accessed in order that the banks A and B are alternately accessed. Fast frame access is accomplished.
