Patent ID: 7890907

Claim:
A computer program product comprising a tangible computer readable storage medium having computer readable program code for designing a memory circuit having at least one memory cell for interconnection with READ and WRITE word lines, READ and WRITE bit lines, a first supply voltage VDD, and a second supply voltage; said cell comprising: a logical storage element having first and second terminals and a storage element supply voltage terminal configured for interconnection with the first supply voltage VDD; a WRITE access device configured to selectively interconnect said first terminal to the WRITE bit line under control of the WRITE word line; and a pair of series READ access devices configured to ground the READ bit line when the READ word line is active and said second terminal is at a high logical level; wherein: said cell is configured to permit writing of a logical “one” to said logical storage element when the second supply voltage is applied to the WRITE word line and is greater than the first supply voltage VDD, substantially without the use of a complementary WRITE bit line; said computer program product including: computer readable program code for determining a WRITE word line voltage, to be applied to said WRITE word line, sufficient to turn on said WRITE access device under conditions when said logical “one” is to be written; and computer readable program code for storing said voltage in memory in a form for subsequent use.
