An Optimum Paged Interleaving Memory by a Hierarchical Bit Line

With a wide spread of 32 bit personal computers, a simple structure and high performance memory system have been highly required. In this paper, a memory block is constructed by using a modified hierarchical bit line in which the DRAM bit line and the latch which works as a SRAM cell are integrated by an interface gate. And the new architecture memory DSRAM(Dynamic Static RAM) is proposed by interleaving the 16 memory block. Because the DSRAM works with 16 page, the page is miss ratio becomes small and the RAS precharge time which is incurred by page miss is shortened. So the DSRAM can implement an optimum page interleaving and it has good compatibility to the existing DRAMs. The DSRAM can be widely used in small computers as well as a high performance memory system.
