Attacking memory-hard scrypt with near-data-processing

In a traditional DRAM-based main memory architecture, a memory access operation requires much more time and energy than a simple logic operation. This fact is exploited to build time-consuming and power-hungry memory-hard cryptographic functions that serve the purpose of hindering brute-force security attacks.
