ABSTRACT:
A dynamic random access memory arrangement for storing digital television signal data under control of a system clock signal CK and input address signals A0 to A17 associated with the data, has a dynamic random access memory having a data input and a data output for the data, and an address input for the input address signals, the dynamic random access memory being controlled by a write enable signal WE, a row address strobe signal RAS and a column address strobe signal CAS, and a logic circuit is provided to derive the signals WE, RAS and CAS from the system clock signal CK with respective timings each determined by a leading edge of a pulse of the system clock signal CK and delay devices.
