Abstract:

Memory systems may include a programmable bit control unit suitable for defining read-write properties to locations in a base address register (BAR) memory, a read-write switch suitable for receiving a memory access request, and identifying whether the memory access request is a read access or a write access, and an access control unit suitable for receiving the memory access request from the read-write switch when the memory access request is identified as a write access, determining a read-write property associated with the write access, and processing the write access to a location in the BAR memory with a defined read-write property that is the same as the determined read-write property associated with the write request.
