Problems solved by technology

In contrast, SSDs have no mechanically moving parts, and thus have no associated risk of mechanical component failure
Also, HDDs have slower seek times (time to access a target memory location) than SSDs

Abstract

Disclosed is a hybrid storage system with a control module embedded solid-state memory. A hybrid control module includes a host interface control module configured to transfer data to and from a host interface. A first embedded multi-media card (eMMC) interface is configured to (i) connect to a second eMMC interface of a control module embedded solid-state memory (SSM) and (ii) transfer the data between the hybrid control module and the control module embedded SSM. A buffer management module is (i) in communication with the host interface control module, the first eMMC interface and a disk access control module and (ii) configured to buffer the data in volatile memory. The data is received by the buffer management module and from at least one of the host interface control module, the first eMMC interface, or the disk access control module.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 333,339, filed May 11, 2010, entitled "SATA HDDWITH eMMC FLASH DRIVE." The entire disclosure of the aforementioned application is hereby incorporated by reference. technical field [0003] The present invention relates to non-volatile memory storage systems, and more particularly to hard disk drives and solid state drives. Background technique [0004] The background description provided herein is for the purpose of generally presenting the context of the disclosure. Neither the work of the presently named inventors, to the extent described in this Background section, nor described as prior art at the time of filing, is admitted, either expressly or by implication, to be prior art to the present disclosure. [0005] A hard disk drive (HDD) may include an HDD control module (or HDD system on chip (SOC) controller) having a host interface and a h...
