This three-part FAQ series began by considering “Memory Basics – Volatile, Non-volatile and Persistent.” Part two looked at “Memory Technologies and Packaging Options.” Recently developed persistent memory technologies, three-dimensional packaging for memories, advanced multicore processors, demands to process larger and larger datasets and databases, and artificial intelligence are driving the emergence of a new category […]

More than wireless: 5G deployment needs power and fiber
In this video, 5G Technology World interviews Corning’s Michael O’Day about composite cables use to deliver both power and light to 5G small cells.
Westinghouse and the fail-safe train air brake, Part 4: Post-Westinghouse
The story of Westinghouse Electric and affiliates does not end with its bankruptcy, but it does change dramatically. It is a twisting tale of getting into new markets, abandoning old ones, having some successes, and having some abysmal failures, which completely transformed what remained. A few of the many highlights and developments include: setting up […]
Memory technologies and packaging options
Solid-state memory devices are available in a wide variety of standard package styles that they have in common with other semiconductor devices, including DIP, TSSOP, DFN, WLCSP, and many others. And various packages are offered in plastic, glass, ceramic, and metal containing one or more devices. They are also available in hermetically-sealed packages and non-hermetic […]
Memory basics – Volatile, non-volatile and persistent
Computers, gaming consoles, telecommunications, automobiles, industrial systems, and myriad electronic devices and systems rely on various forms of solid-state memory for operation. Designers need an understanding of the various options for volatile and non-volatile memory devices to optimize the performance of systems. A new form of solid-state memory called persistent memory (PMEM) has recently emerged […]
Take the 5G Technology World August Quiz
Welcome to the first monthly 5G Technology World quiz. So, you think you know 5G? The quizzes, sponsored by Keysight Technologies, will highlight a different aspect of 5G each month through December 2020. The quiz is interactive; it will tell you which questions you answered correctly or incorrectly. Each month, we’ll select five people who […]
Westinghouse and the fail-safe train air brake, Part 3: Electric brake control
The man who brought fail-safe brakes to railroads once had a major role in the 20th-century industry, but a combination of events and decisions have left only his braking system as a recognized legacy. Thus far, we have looked at the classic, and still widely used fail-safe pneumatic brake (Part 1 and Part 2) However, […]
A fractional Fourier Transform? Yes, there is such a thing.
The Fourier Transform, outlined by French mathematician and physicist Joseph Fourier (1768-1830) in The Analytic Theory of Heat (1822), asserted that any function of a variable, whether continuous or discontinuous, can be expanded in a series of sines of multiples of the variable. His focus at the time was the propagation of heat in an […]
Westinghouse and the fail-safe train air brake, Part 2: The solution
The man who brought fail-safe brakes to railroads once had a major role in the 20th-century industry, but a combination of events and decisions have left only his braking system as a recognized legacy. Part 1 established the need for a reliable, fail-safe braking system. This part looks at the system design in more detail, […]
Westinghouse and the fail-safe train air brake, Part 1: The problem
The man who brought fail-safe brakes to railroads once had a major role in the 20th-century industry, but a combination of events and decisions have left only his braking system as a recognized legacy. Some innovations seem so obvious and pervasive that we assume they have always been with us, but, of course, that is […]
