AI Technical Summary

Benefits of technology

This approach enhances data processing efficiency, reduces power consumption, and minimizes data transfer between the storage device and host, improving filtering speed and reducing the host's processing load.

Problems solved by technology

Volatile semiconductor memory devices may perform read and write operations at a high speed, but lose stored contents at power-off.

Abstract

A storage device may include a main storage part including one or more memories; and a controller configured to control an overall operation of the main storage part. The controller includes a filter manager configured to store data format information and a filtering condition provided from a host; one or more stream filters configured to search and project data stored in the one or more memories in parallel in response to a control of the filter manager to produce searched and projected data; and a merge filter configured to merge the searched and projected data of the one or more stream filters in response to the control of the filter manager.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a divisional application based on pending application Ser. No. 13 / 599,052, filed Aug. 30, 2012, which in turn is a continuation-in-part of application Ser. No. 13 / 187,867, filed Jul. 21, 2011, now abandoned.[0002]This application claims the benefits, under 35 U.S.C §119, of Korean Patent Application No. 10-2011-0086933, filed Aug. 30, 2011, and Korean Patent Application No. 10-2010-0084969, filed Aug. 31, 2010, the entirety of which is incorporated by reference herein.BACKGROUND[0003]1. Field[0004]Exemplary embodiments relate to a data storage device. More particularly, embodiments relate to a semiconductor memory-based storage device and a stream filtering method thereof.[0005]2.
