TRACKING WORST CASE MEMORY CELLS BY SUPPRESSING TRACKING WORDLINE VOLTAGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240379154 titled 'TRACKING WORST CASE MEMORY CELLS BY SUPPRESSING TRACKING WORDLINE VOLTAGE
Simplified Explanation: The memory macro described in the patent application includes a tracking wordline driver that drives a wordline with a suppressed voltage, causing the memory cells to emulate the slowest cells in the array.
- The memory macro includes a tracking wordline driver that drives a wordline with a suppressed voltage.
- The suppressed voltage is lower than the voltage used in the memory array.
- The suppressed voltage is held below the drain supply voltage.
- Suppressing the voltage on the tracking wordline causes memory cells to emulate the slowest cells in the array.
- The tracking wordline with suppressed voltage can be subjected to a mimicked wordline load.
- The tracking wordline with suppressed voltage and the mimicked wordline load can be used for write tracking.
- The tracking wordline with suppressed voltage can also be used as input to a write delay circuit for timing write operations.

Original Abstract Submitted
a memory macro includes a tracking wordline driver that drivers a wordline with a suppressed voltage. the suppressed voltage is made lower than the voltage used to drive wordlines in the memory array by an amount that a tracking wordline is driven with a suppressed voltage, which is a voltage that is held below the drain supply voltage. suppressing the voltage on the tracking wordline causes tracking memory cell with average cell characteristic to emulate the slowest memory cells in a memory array. the tracking wordline with the suppressed voltage may be subjected to a mimicked wordline load. the tracking wordline with the suppressed voltage and the mimicked wordline load may also be used to enable a mimicked write drive used in write tracking. the tracking wordline with the suppressed voltage may also be used as input to a write delay circuit that times write operations.
