摘要:
A volatile memory array using vertical thyristors is disclosed together with methods of operating the array to read, write, retain and refresh data stored therein.
摘要:
Some embodiments include memory devices having a wordline, a bitline, a memory element selectively configurable in one of three or more different resistive states, and a diode configured to allow a current to flow f rom the wordline through the memory element to the bitline responsive to a voltage being applied across the wordline and the bitline and to decrease the current if the voltage is increased or decreased. Some embodiments include memory devices having a wordline, a bitline, memory element selectively configurable in one of two or more different resistive states, a first diode configured to inhibit a first current f rom flowing from the bitline to the wordline responsive to a first voltage, and a second diode comprising a dielectric material and configured to allow a second current to flow f rom the wordline to the bitline responsive to a second voltage.
