Abstract:
Read stability of a memory is enhanced in low voltage operation mode by selectively boosting a cell supply voltage for a row of memory cells. The boosted voltage results from a capacitive coupling to the word line in that row. The capacitive coupling is implemented by running the metal line of the power supply line for the cell supply voltage and the metal line for the word line adjacent to each other in a common metallization level. The selective voltage boost is controlled in response to operation of a modified memory cell exhibiting a deteriorated write margin. An output of the modified memory cell is compared to a threshold to generate a signal for controlling the selective voltage boost. Word line under-voltage circuitry is further provided to control application of an under-voltage to the word line.

Claim (Index 2):
The memory circuit of  claim 1 , wherein the word line under-voltage circuit is configured to delay application of the under-voltage to the word line such that a drive voltage on the word line is controlled by the word line driver circuit to a full voltage level during an initial period and after said initial period the word line under-voltage circuit controls application of an under voltage level which is less than said full voltage level to the word line.
