Abstract
A dual port memory comprising a memory array, a first address circuit, a second address circuit, a timing circuit, a first data circuit and a second data circuit. The memory array may be configured to (i) write information to a first port or (ii) read information from a second port in response to (i) one or more first timing signals and (ii) one or more second timing signals. The first address circuit may be configured to present one or more first control signals in response to one or more first address signals. The second address circuit may be configured to present one or more second control signals in response to one or more second address signals. The timing circuit may be configured to present the one or more first timing signals and the one or more second timing signals in response to the one or more first control signals and the one or more second control signals. The first data circuit may be configured to read or write information from the first port of the memory array. The second data circuit may be configured to read or write information from the second port of the memory array.
