Abstract
A system includes a non-volatile mass storage unit, e.g., a flash memory device and/or a hard drive unit for instance. A memory device is used as a high speed data buffer and/or cache for the non-volatile storage unit. The memory device may be non-volatile, e.g., magnetic random access memory (MRAM) or volatile memory, e.g., synchronous dynamic random access memory (SDRAM). By buffering and/or caching the write data, fewer accesses are required to the mass storage device thereby increasing system performance. Additionally, mechanical and electrical degradation of the mass storage device is reduced. Certain trigger events can be programmed to cause data from the memory device to be written to the mass storage device. The write buffer contents may be preserved across reset or power loss events. The mass storage unit may be a data transport layer, e.g., Ethernet, USB, Bluetooth, etc.
