Embodiments of the present invention receive I/O commands expressed in either vendor-specific or non-vendor-specific protocols and normalize them into a common format for execution by different memory devices. Embodiments of the present invention identify these I/O commands using parameters common to both types of protocols. In this fashion, embodiments store normalized commands in data structures for execution by memory devices in which the normalized commands represent instructions for performing an action corresponding with execution of the original I/O command. Accordingly, embodiments of the present invention save resources with respect to hardware and software maintenance costs.

Method and system for a common processing framework for memory device controllers

Embodiments of the present invention are operable to efficiently schedule memory device commands, such as flash memory device commands, while taking into account the interdependencies of processing such commands. As such embodiments of the present invention order commands to make sure that data is written and read from memory devices in a coherent fashion using command groups. Commands within such command groups are scheduled concurrently or in parallel. In this fashion, embodiments of the present invention promote efficient execution of memory device commands while maintaining any required arbitrary ordering requirements.
