Abstract
A memory with data array (e.g., L2 cache) addressable in rows and columns and techniques to access data therein are proposed. Unlike conventional data arrays, the proposed memory allows data access to be initiated based on a row (or set) address even though the column (or way) address is not yet available. When the column address is determined, it can be used to select the correct data. Since the data access is started prior to determining the column address, memory access latency is reduced.
