ABSTRACT:
A field programmable gate array includes programmable function units (PFUs) that may function as either a logic block or a random access memory (RAM). Each PFU has a write-port enable input when the PFUs are being used as user RAM units. In addition, each PFU includes a write-strobe input. The write operation is accomplished when both the write-port enable input and the write-strobe input are active. This technique allows a reduction of logic gates and control signal conductors. In many cases, these advantages allow for higher system operating frequencies and more gate capacity at a lower cost.
