The memory splitter chip includes logic for managing the transmission of data between the PPU and the DRAM units when the transmission frequencies and the burst lengths of the PPU interface and the DRAM interfaces differ. Specifically, the memory splitter chip implements an overlapping transmission mode, a pairing transmission mode or a combination of the two modes when the transmission frequencies or the burst lengths differ."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Increasing memory capacity of a frame buffer via a memory splitter chip","description":"The memory splitter chip couples multiple DRAM units to the PPU, thereby expanding the memory capacity available to the PPU for storing data and increasing the overall performance of the graphics proc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8489839","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.
