This can help protect against potential security attacks which exploit cache timing side-channels to gain information about allocations into the cache caused by speculative memory accesses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speculative cache storage region","description":"An apparatus (2) comprises processing circuitry (4) to perform speculative execution of instructions; a main cache storage region (30); a speculative cache storage region (32); and cache control circu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11461243","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
