Where does it say that? On-board SRAM would be very strange, as it's incredibly expensive and not at all performant compared to DRAM.

From the paper's abstract: This allows fitting the model into on-chip SRAM cache rather than off-chip DRAM memory

Exactly, that says "on-chip SRAM" not "on-board SRAM". Very different things, and my point stands.

Pretty sure from the context the OP was saying on board the chip.
