As DRAM density keeps increasing, more rows need to be protected in a single refresh with the constant refresh number. Since no memory access is allowed during a refresh, the refresh penalty is no longer trivial and can result in significant performance degradation. To mitigate the refresh penalty, a Concurrent-REfresh-Aware Memory system (CREAM) is proposed in this work so that memory access and...
Compared to the traditional DRAM technology, floating body DRAM (FBDRAM) has many advantages, such as high density, fast access speed, long retention time, etc. More important, FBDRAM is compatible with the traditional CMOS technology. It makes FBDRAM more competitive than other emerging memory technologies to be employed as on-chip memory. The characteristic variance of memory cells caused by process...
In the current power energy environment, this paper combined the characteristics of the power energy industry, established the evaluation index system of the listed energy companies' growth ability, used the entropy value method to determine the dynamic index weight, combined with the ideal point method, three quarters of financial data in 2009 of five energy companies as the original data. Using...
