  • Memory fault detection
    Patent number: 11119874
    Abstract: A memory fault detection method includes: receiving a first interrupt signal sent when a count value of a first leaky bucket counter of a server reaches a first threshold; disabling an interrupt switch of the first leaky bucket counter; enabling the interrupt switch of the first leaky bucket counter after the interrupt switch of the first leaky bucket counter has been disabled for a preset time and the count value of the first leaky bucket counter is reset to zero; receiving a second interrupt signal sent when a count value of a second leaky bucket counter reaches a second threshold; if the second leaky bucket counter and the first leaky bucket counter are a same leaky bucket counter, and the second rank and a first rank are a same rank, determining that a hardware fault occurs in the first rank.
