If radiation particles hit the sensitive nodes of a standard 6T SRAM cell, the data stored in the cell are flipped, resulting in a single event upset. …

WebDRAM requires 1 transistor per bit. DRAM is extremely dense, but very slow. It has a single port that’s used for reading and for writing. SRAM is “static” RAM: it holds data forever. The data is stored in two inverters driving each other in a loop, and to write new data, stronger transistors overpower the tiny ones in the inverter. WebApr 16, 2024 · Apr 15, 2012 at 20:17. If you use a 40,960Khz sampling rate, then a 13-bit counter would loop every 1/5 second.
