Abstract:
A multi-port memory, comprising: a plurality of ports, each port including port input logic that generates a write enable value from received control signals, and a delay stage coupled to store the write enable value from the input stage, and configured to force the write enable value to a disable state in response to an asserted busy signal of the port; and an arbitration circuit coupled to the ports that arbitrates contending accesses to the ports by de-asserting a busy signal to one port, and asserting a busy signal for all other ports.
