QRP operation - Wikipedia

In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. The term QRP derives from the standard Q code used in radio communications, where "QRP" and "QRP?" are used to request, "Reduce power", and ask "Should I reduce power?" respectively. The opposite of QRP is QRO, or high-power operation.

Why QRP?

The QRP Q signal was created to mean "Shall I reduce power?" but has since been adopted by the enthusiasts of low-power operation as their banner. QRP has come to mean 5 W or less output for CW, or 10 W PEP output or less for SSB. Most amateur organizations and contests embrace these as the official QRP limits.

Hybrid GC-eDRAM/SRAM Bitcell for Robust Low-Power ...

Abstract: Conventional static random access memory (SRAM) suffers from high leakage power when implemented in advanced CMOS nodes, while modified bitcells or assist techniques are required to achieve robust low-voltage operation. Gain-cell eDRAM (GC-eDRAM) is an interesting area-efficient alternative to SRAM, but requires refresh cycles and typically a boosted write word-line (WWL).
