Claim Text:
1. A non-volatile memory cell, comprising: a p-channel non-volatile transistor having a source and a drain defining a channel and a gate overlying the channel; an n-channel non-volatile transistor having a source and a drain defining a channel and a gate overlying the channel, the drain of the p-channel non-volatile transistor connected to the drain of the n-channel non-volatile transistor; and in at least one of the p-channel non-volatile transistor and the n-channel non-volatile transistor, a lightly-doped drain region extending from the drain towards the channel, and a lightly-doped drain region extending from the source towards the channel, the lightly-doped drain region extending from the source having a higher doping level than the lightly-doped drain region extending from the drain.
