Abstract:
본 발명은 데이터 저장 장치 및 그것을 포함하는 컴퓨팅 시스템에 관한 것이다. 본 발명의 실시 예에 따르면, 데이터 저장 장치는 데이터를 저장하기 위한 저장 매체와 상기 저장 매체를 제어하도록 구성된 컨트롤러를 포함한다. 상기 데이터 저장 장치는 호스트로부터 제공되는 논리 어드레스를 상기 저장 매체의 물리 어드레스로 변환하기 위한 어드레스 맵핑 테이블을 상기 저장 매체에 저장된 임시 데이터의 논리 어드레스에 따라 구성한다. 상기 임시 데이터의 어드레스 맵핑 테이블은 상기 저장 매체에 백업되지 않는다. 따라서, 상기 데이터 저장 장치는 상기 호스트의 요청에 대한 응답 시간을 단축시킬 수 있다.
Abstract:
PURPOSE: A data storing device and data storing method are provided to maximize the recycling efficiency of a buffer memory and to minimize the fluctuation by the bank collision of a main storing device. CONSTITUTION: Buffer memory usage of a buffer memory is greater than a predetermined threshold value(S1000). The maximum cost about each page or a super page is calculated(S2000). The page having maximum cost or super-page is selected as a victim cache line(S3000). The execution timing of NPJ is scheduled(S4000).
Abstract:
An adaptive adjustment method of user storage area of a non-volatile memory system comprises the following: a host sends a user area information request order to the non-volatile memory system; the host receives the user area information sent from the non-volatile memory system; the host changes the user area information; and the host sends a user area information setting order to the non-volatile memory system to set the changed user area information to the non-volatile memory system. The non-volatile memory system can control the volume of the user storage area in response to user area information.
Abstract:
A method for operating a flash storage device having a memory array including a first memory region and a second memory region comprises the steps of: receiving region allocation information from a host; and allocating a portion of the first memory region as a dedicated region for storing continuous shooting image data, based on the region allocation information. A write speed for the first memory region is faster than a write speed for the second memory region. [Reference numerals] (S100) Perform initialization; (S200) Perform a continuous shooting operation; (S300) Perform a migration operation
Abstract:
PURPOSE: A storage apparatus, stream filtering method, and data storage apparatus including a non-volatile memory apparatus are provided to offer an effective data processing function by effectively merging processing results through the merger filter. CONSTITUTION: A filter manager(23) stores material type information and filtering condition provided from a host. Stream filters(26_1-26_N) extracts and searches data stored in the memory units of a main storage unit by responding to the control of the filter management unit. A merge filter(25) merges a extraction result with searching result searched from the stream filter by responding to the control of the filter management unit. The material type information and the filtering condition are freely established by the host.
