WebRead/Write Figure 8-4 shows the read/write operations of an SRAM. To select a cell, the two access transis-tors must be “on” so the elementary cell (the flip-flop) can be connected to the internal SRAM cir-cuitry. These two access transistors of a cell are connected to the word line (also called row or X address). WebFeb 9, 2024 · In SRAM cells, as the size of transistors and the distance between transistors decrease rapidly, the critical charge of the sensitive node decreases, making SRAM cells more susceptible to soft errors. 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. … chelsea felts
