Abstract
본 발명은 다이나믹 램 메모리(DRAM)를 사용하는 컴퓨터 시스템에서 다이나믹 램 메모리(DRAM)를 액세스 제어하는 장치에 관한 것으로 특히 인터리브 메모리 모드(INTERLEAVED MEMORY MODE)에서 메모리 제어 효율을 높일 수 있도록 한 다이나믹 램 메모리(DRAM)의 액세스 제어장치에 관한 것이다.The present invention relates to an apparatus for access control of a dynamic RAM memory (DRAM) in a computer system using the dynamic RAM memory (DRAM), and in particular, a dynamic RAM memory for improving memory control efficiency in an interleaved memory mode (INTERLEAVED MEMORY MODE). (DRAM) relates to an access control device.
종래의 다이나믹 램 메모리(DRAM) 액세스 장치에 의하면 메모리 액세스가 시이퀀셜하게 이루어지기 때문에 뱅크를 분리하여 설계한 효과가 제한적이고, 메모리를 액세스하는 프로그램은 대부분 연속적인 어드레스를 사용하는데 비하여 종래의 회로는 뱅크별로 묶어서 메모리 제어신호를 드라이브하기 때문에 다이나믹 램 메모리(DRAM)의 리드 시간이 길어지게 되어 시스템 성능이 저하되는 문제점이 있다.According to the conventional dynamic RAM memory (DRAM) access device, since the memory access is made sequentially, the effect of designing the banks separately is limited, and the program that accesses the memory mostly uses consecutive addresses. Since the memory control signals are grouped by banks, the read time of the dynamic RAM memory (DRAM) becomes long, thereby degrading system performance.
본 발명은 메모리의 액세스(리드)시에 시이퀀셜 액세스의 경우 미리 인접한 메모리를 원하는 데이터 액세스와 함께 동시에 액세스하여 래치하여 두고 이를 연속적인 다음 어드레스 드라이브시에 출력해 주므로서 메모리 액세스 효율을 높이고 이에 따른 시스템의 성능 향상을 기할 수 있도록 한 것으로 다이나믹 램 메모리(DRAM) 액세스 제어장치에 적용한다.In the case of sequential access during memory access (lead), the present invention improves memory access efficiency by simultaneously accessing and latching adjacent memories simultaneously with desired data access and outputting them at successive next address drives. It is used to improve the performance of the system and is applied to the dynamic RAM memory (DRAM) access control device.
