Abstract
A method for intervaled memory transfer access provides periodic authorization signals to a memory access controller. The method cycles between: 1) inhibiting the memory access controller from writing data to a memory until the memory access controller receives a periodic authorization signal to cause the memory access controller to remove the inhibition and write a predetermined amount of data to the memory through a data bus, and 2) releasing the data bus following writing of the predetermined amount of data to the memory by inhibiting the memory access controller from writing further data.
