The SK hynix 512 Gb 176L TLC 3D NAND flash memory device is one of fours dies packaged inside one SK hynix H25T1TC48C NAND flash memory package, which was found on the SK hynix SHPP41-500GM-2 Platinum P41 PCIe NVMe M.2 500 GB solid state drive (SSD). This report is an Internal Waveform Overview (IWO) containing the program, read, and erase waveforms for the SK hynix 512 Gb 176L TLC 3D NAND flash memory device (die markings: H25FTC0). The 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 the signals are recorded during program, read and erase operations while the device is active on the source SK hynix SHPP41-500GM-2 SSD.
