Abstract
A circuit arrangement for providing a variably adjustable time delay of digital signals comprises a matrix-shaped memory arrangement having storage elements with overlapping write/read cycles. A clock-controlled, continuously steppable row selector normally cyclically circulates, but can be reset at any time. The row selector comprises two mutually phase offset signal outputs per selection step which respectively drive a write word line and a read word line of a word of the matrix. Two separate bit lines, a write bit line and a read bit line, are provided per column and are respectively interconnected to all memory cells of a column. The data input for the data signal to be delayed is connectible to all write bit lines via gates individually assigned to the columns, whereby only one of m gates is activated at a time by the column selector.
