Development history and structure analysis of DRAM

The history of DRAM FPM / Edo: mainly used before 1996, SOJ packaging mode, operating frequency and CPU bus asynchronous. SDRAM: start to import DRAM operation frequency and CPU bus frequency synchronization. So it is called synchronous DRAM. Synchronous control technology makes the timing cycle of CPU and memory synchronous, and the overall efficiency of […]

Development and challenge of DRAM and NAND Technology

Semiconductor memory has been widely used, in which DRAM and SRAM are two common forms of memory. The characteristic of DRAM is that it needs to refresh regularly to save data. As long as SRAM stores data, it will not lose data without refreshing. DRAM and SRAM have their own advantages and disadvantages. This paper […]
