Characteristics of dram memory
Web5.5.2 Dynamic Random Access Memory (DRAM) DRAM, pronounced “dee-ram,” stores a bit as the presence or absence of charge on a capacitor. Figure 5.46 shows a DRAM bit cell. The bit value is stored on a capacitor. The nMOS transistor behaves as a switch that either connects or disconnects the capacitor from the bitline. WebDynamic RAM (DRAM) is very popular due to its cost-effectiveness. DRAM stores each bit of information in a different capacitor within the integrated circuit. DRAM chips need just one single capacitor and one transistor to store each bit of information. This makes it space-efficient and inexpensive. [2]
