While there is a potential for disturb when applying high voltages of either polarity across the bit the circuitry needs to be carefully designed to avoid this problem...

I thought current had to go through a spin polarizing layer?

I thought the read current is spin-unpolarized, sensing the resistance - while the write current is spin-polarized, setting the resistance. If that is indeed the case then read-disturb should not be a problem...

If read long enough, the read current spin torque could flip the bit, no?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
