Overview
Flashbolt HBM2E at 3.6 Gbps per pin and 16 GB per stack, serving HPC, FPGA, and networking designs in sustained production.
Flashbolt HBM2E delivers 16 GB per 8-high stack at 3.6 Gbps per pin — about 460 GB/s of bandwidth. While AI training has moved to HBM3-class memory, HBM2E remains designed into FPGAs, network switches, and HPC processors with long production schedules.
For those installed programs, continued HBM2E supply is a lifecycle requirement rather than a performance choice. Samsung maintains production and qualification support, making Flashbolt the practical sourcing route for mid-life HBM2E platforms.
