Patent ID: 10474390

Abstract:
A circuit includes a memory and an address generator configured to generate a write address signal and a read address signal, where the write address signal has a first delay relative to the read address signal. The memory is configured to receive a first plurality of write addresses, from the write address signal, including a first plurality of addresses of the memory in a first order, and write, to the first plurality of write addresses, a first plurality of data words during a first time period. The memory is further configured to receive a first plurality of read addresses, from the read address signal, including the first plurality of addresses in a second order, and read, from the first plurality of read addresses, the first plurality of data words during a second time period. The first and second time periods partially overlap. The first order may be one of a natural order and a modified order, with the second order being the other of the natural order and the modified order, and the modified order may be one of a bit-reversed order and a digit-reversed order. The memory may have different write modes, and may be a read-before-write memory or a write-before-read memory.
