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)
