1. A method for transferring data within a nonvolatile memory system, the method comprising:
programming first data to a nonvolatile flash memory (“NVFM”) over a first path, wherein the first data is associated with a write request received from a host device and is classified as sensitive data, and wherein the first path comprises:
storing the first data in a volatile memory buffer;transferring the first data from the volatile memory buffer to a nonvolatile memory buffer that operates as a persistent random-access memory that preserves data stored therein in the event power to the system is lost, wherein inclusion of the nonvolatile memory buffer enables a size of the volatile memory buffer to be reduced while maintaining the same latency reduction that would be achieved had the volatile memory buffer not been reduced; andtransferring the first data from the nonvolatile memory buffer to the NVFM; reading second data from the NVFM over a second path, wherein the second data is associated with a read request received from the host device and the second path comprises:
transferring the second data from the NVM directly to the volatile memory buffer; andtransferring the second data from the volatile memory buffer to the host device; and programming third data to the (“NVFM”) over a third path, wherein the third data is associated with a write request received from the host device and is classified as non-sensitive data, and wherein the third path comprises:
storing the third data in the volatile memory buffer; andtransferring the third data directly from the volatile memory buffer to the NVFM, bypassing the nonvolatile memory buffer. |
