SYSTEM AND METHOD FOR DYNAMIC ALLOCATION TO A HOST OF MEMORY DEVICE CONTROLLER MEMORY RESOURCES

摘要

Systems and methods for a non-volatile memory (NVM) system to allocate controller memory buffer resources to multiple host functions based on host input are disclosed. The NVM system may include a NVM controller configured to advertise total available controller buffer resources to a host. The NVM system includes host writable controller buffer allocation registers for receiving host selected amounts of available controller buffer resources, where a physical function on the host selects a portion of the buffer resources for itself and also selects portions of NVM system controller buffer resources for each other of the secondary, or virtual, host functions also in communication with the NVM system. In this manner, a host in a non-volatile memory express (NVMe) system may dynamically designate controller buffer resources for itself and all other hosts of the NVM system rather than relying on a static NVM system default distribution of controller buffer resources.
