Methods, design structures, and systems for current mode logic (CML) differential driver ESD protection circuitry

A hardware description language (HDL) design structure encoded on a non-transitory machine readable data storage medium, the HDL design comprising elements that when processed in a computer aided design system generates a machine executable representation of a device for implementing dynamic refresh protocols for DRAM based cache, wherein the HDL design structure further comprises:

• an integrated circuit having a differential driver, the integrated circuit comprising:
• a first driver and a second driver forming the differential driver, the first driver and the second driver are coupled in parallel between a first voltage source and a second voltage source;
• a first switch coupled to the first driver, the first switch is configured to turn off the first driver during an ESD event such that the first driver sustains stress during the ESD event;
• and
• a second switch coupled to the second driver, the second switch is configured to turn off the second driver during the ESD event such that the second driver sustains stress during the ESD event, the second voltage source controls the operations of the first switch and the second switch.
