Samsung Electronics Advances 10nm-Class 7th Gen 1d DRAM Production, Plans to Introduce Devices in First Half of Next Year

2026.06.17 14:38:56

June 17 — Citrini researcher Jukan reports that Samsung Electronics is ramping up preparations to mass-produce its 10nm-class 7th-generation 1d DRAM. The company plans to roll out the required production equipment in the first half of next year, with initial mass production targeted as early as the end of next year. Currently, Samsung’s 1c DRAM has a line width of roughly 11 to 12nm; the upcoming 1d variant will shrink that measurement to 10 to 11nm, a tweak designed to boost both performance and energy efficiency. While this process technology is already fairly advanced, key production equipment remains in the development stage. Samsung and its partners are focused on optimizing yield and performance, and they plan to finalize a more precise timeline for the project by the end of this year. The 1d DRAM will serve as a foundational component of Samsung’s AI memory business, particularly supporting the planned commercial launch of its highly anticipated HBM5E high-bandwidth memory core chips in 2029. This initiative is set to strengthen Samsung’s competitiveness in the global AI chip supply chain.

Aave V3.8 adds reentrancy protection for liquidity pools, and has been deployed on 15 V3 markets.

Lending protocol Aave announced that, following approval from Aave DAO, Aave V3.8 developed by Aave Labs has launched on 15 Aave V3 markets. The update adds new security measures to Aave V3 to meet safety standards. Per a governance proposal submitted by Aave Labs, V3.8 is a security-focused, minimally disruptive upgrade that primarily adds reentrancy locks for pool operations during external callbacks. The protection mechanism leverages transient storage (EIP-1153) to maintain accounting consistency when a single transaction interacts with the pool multiple times, while guarding against theoretical reentrancy attacks. Thanks to the use of transient storage, the associated gas overhead remains low. The upgrade covers active Aave instances across 15 blockchains: Ethereum, Plasma, Avalanche, BNB Chain, Monad, Base, Arbitrum, Mantle, X Layer, Polygon, Linea, Optimism, Gnosis, MegaETH, and Celo. Aave Labs clarified that flash loans can still be combined with pool operations such as liquidations in the same transaction, but flash loans cannot be initiated mid-other pool operations. The version passed audits by Certora and third-party firms before moving to on-chain governance voting.
