This paper presents a new architecture SSD based on NVMe (Non-Volatile Memory express) protocol. The NVMe SSD promises to solve the conventional SATA and SAS interface bottleneck. Its aimed to present a PCIe NAND Flash memory card that uses NAND Flash memory chip as the storage media. The paper analyzes the PCIe protocol and the characteristics of SSD controller, and then gives the detailed design of the PCIe SSD. It mainly contains the PCIe port and Flash Translation Layer.

In this paper, we analyzed the endurance of Nand Flash memory and then proposed a level adjusting scheme to use the MLC Flash dynamically to storage different amount of data levels through the entire lifetime. The result shows that the MLC SSD adopting this method could be totally written 4.8X more data than conventional MLC SSD and 16.5% more than SLC SSD.

A triple-level-cell (TLC) STT-RAM architecture was proposed basing on parallel MLC MTJ and serial MLC MTJ. A TLC STT-RAM cell can store three bit which will offer higher capacity density compared with SLC STT-RAM. The write process is also analyzed that it contains three types of basic states transitions. Through mapping soft, medium and hard domains to three individual cache lines, the access to soft lines can perform as accessing SLC STT-RAM-based cache. The amount of three-step operations is also much reduced. .

Data acquisition and record system plays an important role in signal processing. For the wideband signal acquisition and processing application, such as 3G/4G Base Stations, Wideband Microwave Backhaul, Military Communications, and RADAR, the need for high speed and smart software-defined radio (SDR) test platform is growing. In this paper, we implement a high compact form factor data acquisition and storage system used for the wideband signal application development. In order to implement high compact, low power and high speed real-time data storage, we use a PCIe-based switch architecture and leverage the Flash array as the storage part. The system supports RF sampling directly and offers a 16TB solid state storage module which could be read and write at the sustained speed of 12.8GB/s.

RAM disk uses the memory of a computer to construct a high speed, high reliable storage space. Though it is useful, there is little information on the development of RAM disk, especially on Microsoft Windows platform. On Windows platform, RAM disk has to be realized though writing Windows drivers. Implement drivers for Windows is a challenging task that only a small group of programmer can handle for many years. Now, with the new Windows Driver Foundation (WDF), this task is much easier. In this paper, Microsoft’s skeleton RAM disk driver in Windows Driver Kit (WDK) was analyzed and modified. At last, a full function, resizable RAM disk driver was got.

In Bioelectrical impedance measurement, the impedance accuracy is a very important parameter. With the analysis of general Digital Phase Sensitive Detection (DPSD) algorithm and its error, this paper presents an improved DPSD algorithm. In this method, it firstly decomposes the orthogonal signals which have passed through the networks, and then sums (minus) the relevant signals to get the parameters amplitude and phase. By this way, it can avoid errors caused by filtering operation in general DPSD algorithm. At last, the paper gives a simulation which can be hardware-based achieved. The result proves the effectiveness and feasibility of this improved method.

An implementation of a remote destruction solid state drive (SSD) was introduced in the design. The advanced technology of rapid data destruction, the technology of breakdown the flash with high-voltage pulse and the technology of GSM is combined together. As a result, user can operate through a simple command (text message or a call) to destroy all data in SSD, as long as the user confirms SSD is out of control. The method of erasing data and destroying the flash I/O are both executed, so the data can’t be recovered after destruction. At last, some tests are displayed to verify the performance of the remote destruction SSD.
