A cache memory controller may receive a cache memory access request with a supplemental write command for data smaller than a cache line. The cache memory controller may write supplemental to the portions of the cache line not filled by the data in response to a write cache memory access request or a cache miss during a read cache memory access request. In the event of a cache miss, the cache memory controller may retrieve the data from the main memory, excluding any overfetch data, and write the data and the supplemental data to the cache line. Eliminating overfetching reduces bandwidth and power required to retrieved data from main memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Supplemental write cache command for bandwidth compression","description":"Aspects include computing devices, systems, and methods for implementing a cache memory access requests for data smaller than a cache line and eliminating overfetching from a main memory by writing su","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9612971","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.
