Due to CMOS technology scaling and the need of battery operated devices continues to drive the increase of on-die memory density to meet performance needs in various applications. Meanwhile, the device variation and leakage are increasing as the miniaturization of the transistor continues which also effects the realiability and performance of the device. As a result, it is increasingly challeng...

We examine the Medium Access Control sublayer of the IEEE 802.15.6 Wireless Body Area Network (WBAN) standard, and propose minor modifications to the standard so that linear random network coding can be included to help improve energy efficiency and throughput of WBANs compatible with the standard. Both generation-based and sliding window approaches are possible, and a group-block acknowledgmen...

Disk-oriented approaches to online storage are becoming increasingly problematic: they do not scale gracefully to meet the needs of large-scale Web applications, and improvements in disk capacity have far outstripped improvements in access latency and bandwidth. This paper argues for a new approach to datacenter storage called RAMCloud, where information is kept entirely in DRAM and large-scale...

In the arsenal of resources for computer memory system performance improvement, predictors have gained an increasing role in the past years. They can suppress the latencies when accessing cache or main memory. In paper [1] it is shown how temporal parameters of cache memory access, defined as live time, dead time and access interval could be used for prediction of data prefetching. This paper e...

Visualizing very large volume data has been recognized as a task requiring great effort in a variety of science and engineering fields. In particular, such data usually places considerable demands on run-time memory space. This paper describes an effective 3D compression scheme for very large volume data that exploits the power of wavelet theory. In designing our compression method, we have com...

Database storage systems today are primarily based on two technologies: HDD (hard disk drive) and DRAM (dynamic random-access memory). It is increasingly difficult for these systems to deliver acceptable performance, due to fast expanding data volume, growing energy concern, and cost constraints. The emergence of flash memory has made cost-effective solutions possible. However, conventional sto...

SUMMARY This paper reports a 65 nm 8 Mb spin transfer torque mag-netoresistance random access memory (STT-MRAM) operating at a single supply voltage with a process-variation-tolerant sense amplifier. The proposed sense amplifier comprises a boosted-gate nMOS and negative-resistance pMOSs as loads, which maximizes the readout margin at any process corner. The STT-MRAM achieves a cycle time of 1....

Data access control is an efficient way to make sure the data security in the cloud. Due to data outsourcing and untrusted cloud servers, the data access control becomes a challenging issue in cloud storage systems. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is regarded as one of the most suitable technologies for data access control in cloud storage, because it gives data owners mor...
