Abstract

A random access memory with a data input bus, a data output bus, a random access memory array configured to transfer data to random write addresses and from random read addresses in the random access memory array, an address bus providing the random read addresses and the random write addresses, and a first periodic signal configured to control data transfer operations (i) to the random access memory array in response to a first transition of the periodic signal and (ii) from the random access memory array in response to a second transition of the periodic signal, wherein the second transition of the periodic signal is complementary to the first transition of the periodic signal. One preferred embodiment further includes circuitry operable to write data into and read data from the random access memory array. Other preferred embodiments further include a write data register and/or a read data register. In a further embodiment, each of the data input bus and the data output bus is unidirectional. The invention also concerns a process for reading data from and writing data to a random access memory array.
