1T-1C Dynamic Random Access Memory Status, Challenges, and Prospects
IEEE Transactions on Electron Devices, 2020This article reviews the status, the challenges, and the perspective of 1T-1C dynamic random access memory (DRAM) chip. The basic principles of the DRAM are presented, introducing the key functional aspects and the structure of modern devices. We present

2020 IEEE 20th International Conference on Communication Technology (ICCT), 2020
In this paper, the massive random access scenario that a part of users transmit both common and user-specific information and the others transmit only common information is considered, and a mixed massive random access scheme is proposed. In the proposed scheme, the common information is transmitted by unsourced random access (URA) technique, and the ...

Random access cooperative communication
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008User cooperation has been studied extensively in the literature. This mechanism achieves many of the same gains that can be had by using multi-antenna (MIMO) communications in applications where the size or computational resources of a node are limited.

Broadcast stability in random access
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005We introduce and study the problem of broadcast stability in a network where nodes utilize the ALOHA protocol to gain random access to the channel. We make use of the dominating systems argument used in previous works and also develop a novel method for finding the region of stable arrival rates of packets. The stability region is obtained by analyzing

On Random-Access Data Compaction
Proceedings of the 1999 IEEE Information Theory and Communications Workshop (Cat. No. 99EX253), 2000Consider a binary lID. sequence that consists of K = 2’ blocks of length T. We are looking for a universal compaction method that allows us to decode a certain block by looking only at certain segments in the codesequence. We have investigated a hierarchical method that encodes the source sequence into a codesequence that consists of 2~+1 variable ...

Improving the access time for random access files
Communications of the ACM, 1977Clustering in the key set is decreased by smoothing the key-to-address transformation, and by adding shadow buckets to an open chaining file. The keys are pre-hashed before the address division, to remove the effect of sequential properties in the key set. Shadow buckets in the key search sequence reduce the effect of nonuniformity in file loading, and
