Samsung shifts older mobile DRAM from LPDDR4 and LPDDR4X to EOL
Samsung has reportedly stopped accepting new orders for LPDDR4 and LPDDR4X mobile DRAM. Korean outlet The Elec says the company has already taken its final orders and will only fulfill volumes that were booked earlier. Samsung’s own Semiconductor pages for LPDDR4 and LPDDR4X now show both products as discontinued.
The report says production should continue through the rest of 2026 to cover existing commitments, with line conversion expected after the first quarter of 2027. That lines up with Samsung’s earlier push to reduce exposure to legacy DRAM and move more capacity toward DDR5, LPDDR5, HBM, and other higher-margin memory products.
It was confirmed on the 17th that Samsung Electronics has suspended orders for some low-power mobile DRAMs. The affected products are LPDDR4 and LPDDR4X. The company recently received its final orders. It will only process orders received so far, including this volume. After this, the products will be officially discontinued (EOL: End Of Life).

The Elec says some Samsung MX and Qualcomm designs still use LPDDR4 or LPDDR4X, and it points to Exynos 1330 as one example of a chip that supports LPDDR4X and LPDDR5. Samsung’s current LPDDR catalog lists LPDDR5 at up to 6.4 Gbps, while automotive LPDDR4 and LPDDR4X remain listed at up to 4.3 Gbps, which suggests the move is centered on older mobile parts rather than every remaining LPDDR4-family listing.
The Elec says Samsung may move to LPDDR5 once LPDDR4X supply is exhausted, which would raise memory bandwidth by about 50% versus LPDDR4X on paper.
