sealed class Mem[T <: Data] extends MemBase[T]

A combinational/asynchronous-read, sequential/synchronous-write memory.

Writes take effect on the rising clock edge after the request. Reads are combinational (requests will return data on the same cycle). Read-after-write hazards are not an issue.

Note

when multiple conflicting writes are performed on a Mem element, the result is undefined (unlike Vec, where the last assignment wins)

  31. def suggestName(seed: ⇒ String): Mem.this.type

    Takes the first seed suggested.

    Takes the first seed suggested. Multiple calls to this function will be ignored. If the final computed name conflicts with another name, it may get uniquified by appending a digit at the end.

    Is a higher priority than autoSeed, in that regardless of whether autoSeed was called, suggestName will always take precedence.

    seed

    The seed for the name of this component

    returns
