Abstract: Provided are a method and system for handling unaligned writes in a memory controller. A first write request to a memory device in a queue is processed. The first write request is sent to a read modify write (RMW) engine in response to determining that the first write request is unaligned with respect to a first memory location in the memory device. A second write request that is aligned with respect to a second memory location in the memory device is processed. A determination is made of whether there is one write request pending in the RMW engine to the second memory location. The second write request is executed in response to determining that there is no write request pending in the RMW engine.

Abstract: A memory controller module that includes a memory interface and at least two memory controllers, each memory controller to control a category of memory devices. A circuitry enables the at least two memory controllers to control access to memory devices based on information indicating the category or categories of the memory devices coupled to the memory interface.

Abstract: A memory controller includes a write data module to write user data, parity information, and error correction information in a memory. The memory controller includes a read data module to read the user data and parity information, determine whether there is error in the user data based on the parity information, read the error correction information if there is error as determined based on the parity information.
