2.10. Memory Blocks Asynchronous Clear

The M20K memory blocks support asynchronous clear on output latches and output registers. If your RAM does not use output registers, clear the RAM outputs using the output latch asynchronous clear.

The clear is an asynchronous signal and it is generated at any time. The internal logic extends the clear pulse until the next rising edge of the output clock. When the clear is asserted, the outputs are cleared and stay cleared until the next read cycle.
