2. Just for fun: advances in memory. Below are two RAM devices: ERASABLE MEMORY MODULE B12 SAMSUNG EVO Plus mSo 13 8+X lines 8-X ines X distribution to diodes Y distribution Y o diodes 4 - Y lines 192 diodes Core stack Pins Risers from pins The device shown on the left is the Erasable Memory Unity (EMU) from the Apollo Guidance Computer (AGC), which took men to the moon and back. It had 2048 16-bit words (4kByte), stored in RAM based on magnetic cores. On the right is a 512 GByte MicroSD memory-based disk drive Answer the following questions (a) IHow many of the EMUs would it take to equal the memory of the MicroSD card shown? (b) If the dimensions of each EMU are 5cm x 5cm x 30cm, and the EMUs in part (a) were stacked in a cube, how long would the sides be? c) The dimensions of the MicroSD chip are 11mm x 15mm. If the active memory area is about 1cm2, what is the average feature size of 1 bit of memory? Please express your answer in nm
