Dynamic Random-Access Memory (DRAM) Memory Chips Are Made from Silicon

question 80

Multiple Choice

Dynamic random-access memory (DRAM) memory chips are made from silicon wafers in manufacturing facilities through a very complex process called wafer fabs. The wafers are routed through the fab machines in an order that is referred to as a recipe. The wafers may go through the same machine several times as the chip is created. The data file DRAM Chips contains a sample of processing times, measured in fractions of hours, at a particular machine center for one chip recipe. Calculate the 80th percentile for processing time.

• A) 0.40 minutes
• B) 0.35 minutes
• C) 0.45 minutes
• D) 0.20 minutes
