M88SC26HA/B (HSDIMM®-Lite)

Product Description

M88SC26HA/B is a Hybrid Security DIMM-Lite (HSDIMM®-Lite) device based on JEDEC DDR4 RDIMM architecture. HSDIMM®-Lite consists of a set of 8 Gb DDR4 SDRAMs and a security RCD equipped with Montage’s Security Authorization Management (SAM) mechanism, which provides command/address tracing and data protection for memory systems via security access rule matching and key management. HSDIMM®-Lite has rich features relative to data security, including real-time monitoring of CPU access to memory, tracing and/or blocking of unauthorized access commands, etc. M88SC26HA/B delivers a DIMM-level security solution for the memory systems of demanding servers. It supports data rates up to DDR4-2666 and has flexible capacity options of 16 GB (M88SC26HA) and 32 GB (M88SC26HB).
