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

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

Writes take effect on the rising clock edge after the request. Reads return data on the rising edge after the request. Read-after-write behavior (when a read and write to the same address are requested on the same cycle) is undefined.

Note

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