The following is an Internal Waveform Overview containing the program, read, and erase waveforms for the YMTC 1.33 Tb 128L quad-level-cell (QLC) 3D NAND flash memory device (die markings: CEC1A). This device is packaged inside the YMTC YMC4G0W1TbG1AA1C0 NAND flash memory package, which was found on the HikSemi HS-SSD-V300 2.5 inch SATA 6 Gb/s 512 GB solid state drive (SSD). This analysis provides an overview of the internal voltages required to program, read, and erase the flash memory cells. The waveform analysis tests the flash in an active probe arrangement and voltage traces of four signals are recorded during program, read and erase operations. The YMC4G0W1TbG1AA1C0 package was removed from the SSD board and operated as a standalone package in a NAND flash programmer while performing the signal measurements.
