DRAM, Rowhammer

Rowhammer is a vulnerability in commodity dynamic random access memory (DRAM) chips that allows an attacker to exploit devices with DRAM memory by repeatedly accessing (hammering) a row of memory until it causes bit flips and transistors in adjacent rows of memory reverse their binary state: ones turn into zeros and vice versa. Continued…

flip flops (bistable gates)

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
flip flop, integrated circuit, Logic gates

Flip-flops, also called bistable gates, are digital logic circuits that can be in one of two states. Flip-flops maintain their state indefinitely until an input pulse called a trigger is received. When a trigger is received, the flip-flop outputs change state according to defined rules and remain in those states until another trigger is received. Continued…
