Z-RAM

The New SOI-Based Memory Technology In the electronics industry today there are two commonly used high-speed memory types: static RAM (SRAM) and dynamic RAM (DRAM). Traditionally, SRAM embedded memory has been the designer’s choice for fast memory, but since a typical SRAM bitcell is comprised of six transistors, that benefit comes at the expense of cost and silicon area. Embedded DRAM (eDRAM), whose smaller bitcell is comprised of a single transistor and single capacitor, offers a much lower cost option, but has higher latency and is typically used further from the processor. While DRAM is fundamental to electronic systems, it does have its limit — namely, its inability to scale to accommodate the migration to smaller, and therefore more advanced, process geometries. This limitation is further complicated by the fact that new application areas for memory are fast appearing, fueled by the popularity of digital home appliances and next-generation mobile devices, the digital convergence of electronic goods and telecommunications, and ever evolving media content.

The John H. Glenn Research Center introduces the Portable Unit for Metabolic Analysis (PUMA), an instrument that measures quantities indicative of human metabolic function. The PUMA makes time-resolved measurements of temperature, pressure, flow, and the partial pressures of oxygen and carbon dioxide in breath during inhalation and exhalation. Click here for more info.

Tech Needs of the Week

A company is seeking a powder slurry coating technology, where substrates are coated with powder slurry in an organic binder and then heat treated to diffuse the coating onto the substrates. Any proposed powder slurry coating technology should involve a powder composition based on Co-based or Ni-based alloys. It should be a water-based, environmentally friendly binder suitable for use on Fe-based alloy substrates. The technology should result in dense, crack-free, and metallurgically bonded coatings.
