Error rates are typically proportional to the ratio of operating time to decoherence time, hence any operation must be completed much more quickly than the decoherence time.
PCIe has numerous improvements over the aforementioned bus standards, including higher maximum system bus throughput, lower I / O pin count and smaller physical footprint, better performance-scaling for bus devices, a more detailed error detection and reporting mechanism ( Advanced Error Reporting ( AER ) ), and native hot-plug functionality.
Error correction codes are often used to increase reliability: even if one or more cells is damaged so it is unreadable, the message can still be read.
