Heterogeneous hybrid memory module, system and storage method

Abstract

The invention discloses a heterogeneous hybrid memory module, a system and a storage method. The heterogeneous hybrid memory module comprises a memory controller, a storage unit array and a buffer region, wherein the memory controller is used for receiving a write / read request of a processor, detecting unit spaces corresponding to pages accessed by the processor according to address information in the write / read request, controlling data to be written into the storage unit array from the processor through the buffer region, or controlling the data to be read to the processor from the storage unit array through the buffer region; the storage unit array is used for storing the written / read data in a multi-page manner according to a first storage type; the buffer region is used for storing the written / read data by setting a plurality of the unit spaces corresponding to the pages according to a second storage type; and the read / write rate of a second storage mode is higher than that of a first storage mode. The heterogeneous hybrid memory module has the beneficial effects that an external storage device and a memory share the equal data bandwidth and are no longer accessed through IO, so that the access efficiency of external storage is greatly improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a heterogeneous mixed memory component, system and storage method. Background technique [0002] The traditional server adopts a two-level storage mechanism. The CPU first searches for the required data from the internal storage unit, and then retrieves the data from the external storage (hard disk) when the data is not in the memory. The speed difference between CPU and memory is solved by multi-level cache, but the speed gap between memory and external memory is getting bigger and bigger, reaching 100,000 times. In the case of big data processing, frequent access to external memory will lead to a significant decline in the performance of the entire system, becoming a bottleneck in system performance and restricting the speed of data access. [0003] The existing technology adopts RAID0 (RAID0 is also called Stripe or Striping, which represents the highest storage performance...
