What should be used to represent physical chips e.g. eMMC or NAND

[chrishargreaves]

The following SOLVE-IT techniques could do with a representation of physical storage chips:

Chip-off

(output is eMMC typically but could be NAND)

Access data from a desoldered eMMC via a chip reader
https://explore.solveit-df.org/#DFT-1029
(input would be eMMC)

Is there a representation that is missing or is this detail out of scope and should just be observable:Device or observable:StorageMedium?
