Abstract
Disclosed is a read-out circuit for use with semiconductor memory devices such as image memories comprising both a group of randomly accessible memory cells and serial registers that are serially accessed. The read-out circuit contains presetting means for presetting the output side of a column selector of the memory before signal read-out. This prevents the drop in performance margin attributable to boosted parasitic capacity on the column selector output side.
