“…Caches are designed to keep frequently used data and instructions close to the processing unit to avoid power-hungry and slow access to main memory. Almost all modern CPU cores, from ultra-low power chips, such as the ARM Cortex-A53 [1] to Circuit designs proposed in [14,15] combine data duplication/triplication with error correction schemes to increase reliability while reducing supply voltage. The design can save energy through voltage scaling and ensure reliable behavior in harsh environments, however, with the cost of high area overhead of additional memory cells.…”

“…To counter this, radiation hardening techniques are employed to enhance the resilience of SRAM cells against such errors. These techniques, such as redundant circuitry, error correction codes, and error detection and correction mechanisms, are employed to ensure reliable operation even in radiation-prone environments [6][7][8][9][10].…”

“…In this chapter, we design a level one cache which can tolerate very high bit failure rates of ultra-low voltage execution with minimum overhead, and without harming the cache capacity in the nominal mode. To this end, we present Flexicache, a new cache design which avoids the problematic aspects of coding and in-cache replication through a twotiered approach [64], [65]. First, Flexicache proposes a circuit-driven solution that duplicates/triplicates all the available cache lines and achieves read/write accesses to multiple lines without increasing access latency and with a minimum increase in the access energy.…”
