Embodiment Construction

[0029] The SSD device according to one aspect of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] 1. Summary

[0031] In the example of the present invention, a RAID system is realized in one SSD device by arranging the first and second memory modules and a control board mounted with a module controller that determines the control method of these modules in one SSD device.

[0032] Furthermore, each of the first and second memory modules has a memory chip and a memory controller for controlling the memory chip on one side of the module substrate. That is, since the first and second memory modules have the same function, for example, existing cells whose performance is guaranteed can be included in each memory module.

[0033] Therefore, costs such as development costs and material costs for new investment can be suppressed, and a low-cost RAID system that is less prone to failure during assembly can be realized.

Abstract

A SSD apparatus includes a first memory module, a second memory module, a module controller which determines a method of controlling the first and second memory modules, a control board mounted with the module controller, a first connector which a module board of the first memory module and the control board are connected to, a second connector which a module board of the second memory module andthe control board are connected to, and an interface device connected to the control board. A memory chip and a memory controller are mounted on one surface of the module board of each of the first and second memory modules. The other surface of the module board of the first memory module is faced to the other surface of the module board of the second memory module.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Priority Patent Application No. 2008-244811 filed on September 24, 2008, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an SSD (Solid State Drive or Solid State Disk: solid state drive) device. Background technique [0004] The SSD device is a large-capacity data storage device using a nonvolatile semiconductor memory such as a NAND flash memory. Since SSD devices have the same interface as magnetic recording HDDs (Hard Disk Drives), they have recently begun to be used in personal computers, servers, and the like due to increased capacity and lower prices. [0005] However, there is a RAID (Redundant Arrays of Inexpensive Disks: Redundant Array of Inexpensive Disks) system as a scalable usage method of HDDs (see, for example, Japanese Patent Application Laid-Open N...
