Abstract
In the era of Covid-19 New Normal, our daily activities are rapidly moving from off-line to on-line. Recent advancements in high speed network, AI / machine learning, and high-performance computing helped this transition successfully, thus enabling many data-driven services/products such as online business, autonomous vehicles, metaverse, and etc. However, the data generated from daily life continued to increase exponentially, accompanied with the growing need for higher capacity & performance in storage, computation, and transmission. Data centers those are responsible for massive data storage, have dramatically increased the storage capacity & performance by extensive usage of non-volatile memory-based storage systems. However, such an improvement of capacity & performance has inevitably led to the increase in the power consumption, thus bringing the limited power budget as a system performance constraint. To solve this problem, the storage devices actively use new architectural techniques, such as hardware acceleration and in-storage processing, as well as new power-efficient components fabricated with advanced semiconductor technology. In addition, the server systems also try to achieve power efficiency by using new interface technology such as CXL, which improved the way data is transferred between processors, memory and storage. In this presentation, we first introduce our non-volatile memory storage products & technology, and then explain our approach to achieve power efficiency used in storage architecture & design. Lastly, we present the next-generation storage systems, including SSDs with CXL interface.

Abstract
Neuroscience research into how complex brain functions are implemented at a extra-cellular level requires in vivo neural recording interfaces, including microelectrodes and read-out circuitry, with increased observability and spatial resolution. The trend in neural recording interfaces towards employing high-channel-count probes or 2D microelectrodes arrays with densely spaced recording sites for recording large neuronal populations makes it harder to save on resources. The low-noise, low-power requirement specifications of the analog front-end usually requires large silicon occupation, making the problem even more challenging. One common approach to alleviating this area consumption burden relies on time-division multiplexing techniques in which read-out electronics are shared, either partially or totally, between channels while preserving the spatial and temporal resolution of the recordings. In this approach, shared elements have to operate over a shorter time slot per channel and active area is thus traded off against larger operating frequencies and signal bandwidths. As a result, power consumption is only mildly affected, although other performance metrics such as in-band noise or crosstalk may be degraded, particularly if the whole read-out circuit is multiplexed at the analog front-end input. In this talk, we review the different implementation alternatives reported for time-division multiplexing neural recording systems, analyze their advantages and drawbacks, and point out to strategies for improving performance.

Memory Smarter

Yangsung Joo
Design Research Lab, SK Hynix, Korea

Biography Abstract

Biography
Yangsung Joo is leading the Design Research Lab, SK Hynix. The Lab is developing next LPDDR & DDR DRAMs and researching next memory and solutions. He had worked at numerous memory development projects in global firms, since he received the Master degree in Electrical Engineering from the Korea University, in 1992.
Abstract
Data creation is constantly happening in our world at the enormous rate of growth, throughout the systems such as from the small devices to the larger scale Data Centers. Data ecosystems, where these data are expanding to maintain and sustain our daily lives, have required the much more efficient and effective processing. In order to meet the demands, memory industry has kept scaling up the density, bandwidth and energy efficiency. However, the DRAM industry is facing serious challenges on keeping the scaling trends. Actually, the slower phase in conventional system developments has already been seen by the markets. As most of semiconductor and system industries are pursuing economically optimal solutions, a lot of evolutionary and revolutionary project papers have been published. This talk will show those interesting researches including SK Hynix pathfinding activities, and bring forward collaboration opportunities to the academia and industrial frontiers.
