摘要:
A multiple serial access memory is provided. A dynamic random access memory (30) is addressed to input data thereto and output data therefrom. Rows of data are output from the array (50) in response to address signals (34, 36, 38) provided thereto. A plurality of serial output ports (44, 46, 48) is coupled to the output of the array for selectively latching different rows of data output from the array. The serial output ports (44, 46, 48) are clocked to output the latched data therefrom. In an illustrated embodiment, each of the serial output ports contains a shift register (62, 64, 66, ... 68) having a length equal to the width of the memory array (30). The shift register is responsive to a first timing signal (42, 52) for latching a row of data from the array (30). A second timing signal actuates the shift register to shift a row of latched data. A serial access selector (70) coupled to the shift register outputs a selected portion of the shifted data from the serial output port. The memory has particular application as the frame store for a motion compensated interframe image coding/decoding system.
