ABSTRACT:
A random access memory has: upper and lower address limits, an address input responsive to an address counter, a write enable input, a read enable input, a data input bus, and data output bus. The address counter is supplied with a synchronization signal having a frequency determined by the frequency of a variable frequency data source. A signal having first, second and third values, respectively indicative of the address input of the memory being at the upper limit for the memory address, the lower limit for the memory address and between the upper and lower limits, is derived in response to the count in the address counter. First, second and third oscillators respectively derive first, second and third fixed frequencies such that the third frequency is greater than the second frequency and the second frequency is greater than the first frequency. The first, second and third fixed frequencies are coupled to the address counter while the signal has the third, second and first values.
