Abstract

A data processing system (15) including a synchronous random access memory (30) and a method for accessing the synchronous random access memory are disclosed. A digital processor (20) of the data processing system is coupled to with a system clock circuit (65) that produces a system clock signal for controlling operation of the digital processor. Addressable storage cells within the synchronous random access memory are accessed in response to the system clock signal and an address select signal (ADS) to write data into the storage cells or read data out from the storage cells. Initial row and column addresses are latched into a row address buffer (48) and a column address buffer (49). A number of data bits corresponding to a control signal such as a wrap length (WL) signal are read out from the memory in synchronization with the system clock signal. The synchronous random access memory device may be fabricated as a dynamic storage device or as a static storage device.
