SEMICONDUCTOR MEMORY DEVICE, MOVING VECTOR DETECTING DEVICE, AND COMPENSATION PREDICTION CODING DEVICE

PROBLEM TO BE SOLVED: To enable access simultaneously a plurality of pixel data constituting a pixel block having an arbitrary shape such as rectangle, cross, or the like and to enable change easily a position of the pixel block. SOLUTION: A semiconductor memory device comprises memory blocks of one or two or more. This memory block has a memory cell array consisting of a plurality of memory cells 210 arranged in a matrix state. Regions of a plurality of memory cells 210 consist of a plurality of regions 201a-201e divided in the direction along word lines WL, a plurality of word lines WL consist of a plurality of divided selection lines WLa-WLe divided corresponding to the plurality of divided regions respectively. The memory block has switching mechanism 220 for switching the divided word lines WL activated simultaneously in each divided region. Pixel data of one column is stored in a plurality of memory cells 210 corresponding to each divided word line in the vertical direction or horizontal direction. COPYRIGHT: (C)2003,JPO
