How do voice recorder chips like ISD1020AP work?

How does a chip like the ISD1020AP actually store data without power? I am very curious.

The datasheet tells you how:

"Recordings are stored in on-chip nonvolatile memory cells, providing zero-power message storage."

Basically, the chip is like a flash drive.
