SYSTEMS AND METHODS FOR MAINTAINING MEMORY ACCESS COHERENCY IN EMBEDDED MEMORY BLOCKS

摘要

Enhanced memory circuits are described that maintain coherency between concurrent memory reads and writes in a pipelined memory architecture. The described memory circuits can maintain data coherency regardless of the amount of pipelining applied to the memory inputs and/or outputs. Moreover, these memory circuits may be implemented as dedicated hard circuits in a field programmable gate array (FPGA) or other programmable logic device (PLD), and can be supplemented with user-configurable logic to achieve coherency in a variety of applications.
