The memory device (i) improves current tracking between the device's memory cells and the keeper circuit, (ii) improves Vccmin for memory operations, and (iii) has an efficient circuit layout. The memory device includes a memory array with a plurality of bitlines coupled to the memory cells. The keeper circuit includes a plurality of switches and a current mirror circuit. The plurality of switches is respectively coupled to the plurality of bitlines. The current mirror circuit mirrors a bias current to a plurality of current mirror transistors respectively coupled to the plurality of switches."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory with keeper circuit","description":"A memory device with a keeper circuit is disclosed herein.
