Title:
TERNARY MEMORY CELL AND MEMORY DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/204651
Kind Code:
A1
Abstract:
In a memory device comprising a ternary memory cell, the ternary memory cell may comprise: a first inverter and a second inverter which are cross-connected at a first node and a second node, and comprise a pull-up device and a pull-down device enabling a constant current to pass through during turn-off; a first read transistor and a first write transistor which are mutually connected in parallel between the first node and a first bit line; and a second read transistor and a second write transistor which are written and are mutually connected in parallel between the second node and a second bit line, wherein, as a response to an activated read word line, the first read transistor and the second read transistor may enable a read access current, equal to or smaller than the constant current, to pass through.
