Now, if you look within a DRAM, the circuit behind every DQ pin is made up of a set of parallel 240Ω resistor legs, as shown in Figure 4. Because of the nature of CMOS devices, these resistors are never exactly 240Ω. The resistance is even affected due to voltage and temperature changes. So, they are made tunable.
The $50 to $100 bracket is where most people tend to shop, and this year it’s been dominated by a few interesting trends. Rockchip’s RK3576 has turned up on multiple boards, Qualcomm has made a very strong entrance, and there’s a networking-focused option that doesn’t care about your Geekbench score.，这一点在PG官网中也有详细论述
