Chip Component Analysis

SSD Controller

The prominent markings say this is a flash controller made my Lexar, called DM620. Actually we've identified several factors, in addition to the physical size and design, that led us to believe this is a rebranded Innogrit IG5216 controller. It has four flash channels and supports the NVMe 1.4 specification.


The device ID has actually been adjusted to match the Lexar/Longsys branding, 1D97 is "Shenzen Longsys Electronics Co., Ltd."

SSD Flash Chips

The four 64-layer 3D TLC flash chips are made by Micron. NW964 decodes to MT29F1T08EMCAGJ4.
