Problems solved by technology

However, in many cases, DRAM consumes a lot of power, and the power consumption increases with the increase of DRAM capacity
Therefore, it is currently difficult to achieve further acceleration while saving SSD power consumption
[0006] Here, so far, the problem that high speed and energy saving are difficult to achieve simultaneously has been explained by taking SDD as an example
However, this problem usually occurs in storage systems that use energy-intensive storage media such as DRAM as a cache to store data

Abstract

A memory system includes a first memory that is used as a main memory of a target device, a second memory that has an access speed lower than that of the first memory, a securing section that secures a predetermined area of the first memory as a temporary storage area of the second memory, and a memory control section that receives an instruction to write data into the second memory, temporarily stores the data into the first memory and also transfers the stored data from the first memory to the second memory.

Description

technical field [0001] The embodiments discussed herein relate to a storage system and an information processing device. Background technique [0002] Recently, as a storage device replacing HDD (hard disk drive), so-called SSD (solid state drive) using flash memory as a storage medium has attracted attention (for example, see Japanese Patent Laying-Open Nos. H5-150913, H6-4399 and 2007 -41813). [0003] Since SSDs do not have magnetic disks like HDDs, there is no need for the seek operation time to move the head to the desired track and the time for the head to reach the desired data position in the track. Therefore, SSDs can store and reproduce data faster than HDDs, and therefore, SSDs have attracted widespread attention. Furthermore, unlike HDDs, SSDs do not need to use motors to rotate disks or move heads, resulting in lower power consumption, which is another reason why they have attracted widespread attention. [0004] Here, most SSDs are equipped with DRAM (Dynami...
