Abstract

A memory access technique is provided that may be used in WLAN (Wireless Local Area Network) communication devices. An on-chip memory has multiple memory circuits forming individually addressable memory segments. An arbitration unit arbitrates between multiple requesters, each requesting access to the on-chip memory. The requesters are on-chip circuits and/or external devices. The arbitration unit determines a memory circuit to be accessed for each request that is received from a requester. The determination may be based on a software configurable arbitration scheme. The memory segments may form a bank of single-port SRAM (Static Random Access Memory) devices.
