Data-dependent self-biased differential sense amplifier
Balaji Jayaraman,Thejas Kempanna,Toshiaki Kirihata,Ramesh Raghavan,Krishnan S. Rengarajan,Rajesh R. Tummuru +5 more
TL;DR: In this paper, a memory cell includes a pair of a first transistor and a second transistor providing a differential signal output, and a feedback circuit receives one of: a first signal or a second signal of the differential signals, and generates, in response, a feedback signal which is simultaneously applied to bias each current source load transistor in each the first and second circuit legs to amplify a voltage differential between the differential signal outputs.

Disturb free bitcell and array
Navin Agarwal,Aditya S. Auyisetty,Balaji Jayaraman,Thejas Kempanna,Toshiaki Kirihata,Ramesh Raghavan,Krishnan S. Rengarajan,Rajesh R. Tummuru,Jay M. Shah,Janakiraman Viraraghavan +9 more
TL;DR: In this paper, the memory includes a first device of the cell array which is connected to a bitline and a node and controlled by a word line, and a second device consisting of a third device connecting to a source line and the node and controlling by the word line and a fourth device connecting between the source and node, and the third device isolates and floats the node such that a voltage level of a gate to source of the first device is clamped down by the fourth device to around zero volts.
Patent
