Each RAM cell has a RAM cell structure with a first and second power terminals and configured to operate as a RAM cell when the memory array is in a RAM mode. The ROM cell has the same RAM cell structure in which at least one transistor is modified to cause the ROM cell to have a predetermined logic state. The ROM enable circuit enables bit lines of the ROM cell to control supply voltages provided to the power terminals of the RAM cells so that they settle to predetermined logic states in a ROM mode. The modified transistor has a pseudo transistor structure having a modified substrate that operates as a resistance, such as a doping region in the substrate having the same polarity type as the substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory array with RAM and embedded ROM","description":"A memory array with RAM and embedded ROM including multiple RAM cells, a ROM cell, and a ROM enable circuit.
