“…The low power consumption on the hard disk could be explained by the combined use of cache memory and hard disk in the web portal. These mechanisms can significantly improve both energy efficiency [ 108 ] and performance [ 109 ], avoiding the long waiting time and high power consumption of hard disks’ spin-ups [ 110 ].…”

Usability is key to achieve quality in software products. The client applications with a high score in usability might impact on the power consumption when they are run in a PC. For this reason, energy savings turn to be critical in green software systems. In this paper the relationship between the usability evaluations of the GUIs and the power consumption measurements of the main components of a PC were analysed. A set of 5 web-based personal health records (PHRs) were selected as a case study. The usability assessment was performed by an expert, employing the 14 principles of design by Alan Dix as heuristics. They were scored on a Likert scale after performing a collection of common tasks in the PHRs. At the same time, an equipment to measure the energy consumption of hard disk drive, graphics card, processor, monitor and power supply was used. Spearman’s index was studied for the correlations between the usability assessments and the power consumption measurements. As a results, some weak relationships were found. A total of 5 usability heuristics were observed to may influence energy consumption when they were considered in the implementation of the PHRs. These heuristics were the following ones: consistency, task migratability, observability, recoverability and responsiveness. Based on the results, the usability principles of design cannot always be related to lower energy consumption. Future research should focus on the tradeoffs between usability and power consumption of client applications when they are used in a computer.

“…In 2009, Toshiba demonstrated the first 128 Mb Chain FeRAM samples [13]. The write/read speed of this memory reaches 1.6 Gb/s, which is comparable to that of standard semiconductor DRAM.…”

“…The minimum determinable polarization charge in a capacitor is ~20-30 fC (femtocoulomb) on an area of 10 4 nm 2 (for PbZr 1 -x Ti x O 3 ), which is the physical limit set by the charge distribution discreteness in the crystal lattice of a ferroelectric [31]. This limits the volume of practically accessible planar memory to 128 Mb in the case of PbZr 1 -x Ti x O 3 [13] and to 256 Mb in the case of BiFeO 3 (noncommercial sample from Fujitsu) [14].…”

“…It also enables the concurrent writing of 0 or 1 states without needing to elevate BLs, enhancing write efficiency in MRAM. Figure 3f illustrates a 1T-1R bitcell occupying an area of 20 F 2 [54], which is more compact than earlier FRAM [89,90], STT-MRAM [16,76], and CBRAM [91,92] designs. The RRAM was equipped with a novel sense amplifier and a write-and-verify (WAV) voltage generator to increase the read and write yield.…”

In the era of widespread edge computing, energy conservation modes like complete power shutdown are crucial for battery-powered devices, but they risk data loss in volatile memory. Energy autonomous systems, relying on ambient energy, face operational challenges due to power losses. Recent advancements in emerging nonvolatile memories (NVMs) like FRAM, RRAM, MRAM, and PCM offer mature solutions to sustain work progress with minimal energy overhead during outages. This paper thoroughly reviews utilizing emerging NVMs in microcontroller units (MCUs), comparing their key attributes to describe unique benefits and potential applications. Furthermore, we discuss the intricate details of NVM circuit design and NVM-driven compute-in-memory (CIM) architectures. In summary, integrating emerging NVMs into MCUs showcases promising prospects for next-generation applications such as Internet of Things and neural networks.
