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

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. Determine what the mode processing time is.

A) 0.22
B) 0.24
C) 0.33
D) 0.34
