The basic physics of reading from Flash vs. DRAM are broadly similar, and it's true that reading from SLC flash is a bit cheaper, but you'll still need way high

The basic physics of reading from Flash vs. DRAM are broadly similar, and it's true that reading from SLC flash is a bit cheaper, but you'll still need way higher voltages and reading times to read from flash compared to DRAM. It's not really the same.
