“…As the storage capacity of flash increases, their latency behaviors get worse than before. Specifically, QLC flash [21] requires 2 ms for programming time, which is 10 × higher than an old SLC flash technology [12].…”

“…Solid-state drives (SSDs) using NAND flash memories have been replacing hard-disk drives (HDDs) because of SSD's faster speed and higher density. [1][2][3][4][5][6] Figure 1 depicts the structure of NAND flash memory cells of the two-dimensional (2D) NAND flash. By applying the appropriate voltage to the control gates, select gates, and bit lines, read=write= erase operations are executed.…”

In order to improve performance of solid-state drives (SSDs), hybrid SSDs have been proposed. Hybrid SSDs consist of more than two types of NAND flash memories or NAND flash memories and storage-class memories (SCMs). However, the cost of hybrid SSDs adopting SCMs is more expensive than that of NAND flash only SSDs because of the high bit cost of SCMs. This paper proposes unique hybrid SSDs with twodimensional (2D) horizontal multi-level cell (MLC)/three-dimensional (3D) vertical triple-level cell (TLC) NAND flash memories to achieve higher cost-performance. The 2D-MLC/3D-TLC hybrid SSD achieves up to 31% higher performance than the conventional 2D-MLC/2D-TLC hybrid SSD. The factors of different performance between the proposed hybrid SSD and the conventional hybrid SSD are analyzed by changing its block size, read/write/erase latencies, and write unit of 3D-TLC NAND flash memory, by means of a transaction-level modeling simulator.

“…Therefore, in this work, 100% carrier capture efficiency (i.e., without the penetrating leakage current) is ensured using the slope derived from the incremental-step-pulse programming (ISPP). 8,9) By introducing the ISPP slope as an indicator of carrier capture efficiency, a reliable result has been obtained, that is, the charge centroid moves from the bottom of the charge layer toward the charge layer/block layer interface during avalanche injection. In addition, with the increase in applied electric field, the initial location of available traps shifts from the bottom to the top of the charge layer.…”

The lateral distribution function (LDF) of radio emission from an extensive air shower is considered as the basic signature sensitive to the shower longitudinal development and, as a consequence, to the mass of a primary cosmic ray's particle that initiated a given shower. The peculiarities in the LDF's structure as well as their sensitivity to the height of shower maximum are investigated and explained.
