Abstract
According to one aspect of the invention, a circuit for accessing data in a memory is disclosed. The circuit generally comprises a first port having a read logic circuit and a first output which generates data from the memory. A second port has a read logic circuit and a write logic circuit. A second output is coupled to the second port, and also generates data from the memory. Circuits for separately selecting read and write widths for a port of a memory, such as a random access memory, are disclosed. Finally, other embodiments related to implementing a content addressable memory in a programmable logic device are disclosed. Further, a method of accessing data in a memory is disclosed.
