A free release archive and market-pulse desk for journalists, semiconductor specialists, investors, and operators. Every brief identifies whether it is an official release, an open dataset, or VLSI Korea analysis.
Sorted by the date of the event or underlying release, not by the date it was added to the website.
The published NAND 128Gb fixed reference increased to $28.80 per chip from $26.50 in May; DDR4 8Gb increased to $21.00 from $20.00. Both measures are fixed-price references, not live spot quotes.
Open analysisGovernment release carrying the latest independently dated memory, DRAM, NAND, system-IC, regional export, and fixed-price reference observations used by this workspace.
Open primary sourceThe prior official monthly release preserves the sequence used for revisions, source reconciliation, and month-over-month comparison.
Open primary sourceOfficial source for April product references and export signals. The original reporting basis is retained instead of being relabeled as a spot market quote.
Open primary sourceCEPII BACI provides open-licensed bilateral HS 854232 trade value and reported physical quantity for a long-run global activity view. Customs routes are not final end-use destinations.
Open analysisPublic KISDI material documents the September-to-October change in DDR4, DDR5, and NAND fixed references and provides contemporaneous export context.
Open primary sourceThe platform checks faster than most sources publish, then retains the last valid observation with a visible source date if an upstream release is late or unavailable.

This matrix mirrors the analytical categories readers expect from a professional memory exchange. A category appears in the matrix even when its numeric series cannot legally be redistributed; it never produces an empty or fabricated chart.

Fixed reference, spot, contract, retail, launch, trade, and modeled ASP are separate analytical objects.
Absent or non-redistributable observations are omitted from numeric views, not converted into a flat line.
Published revisions replace snapshots only after unit, period, and series identity reconcile.
The open basket publishes constituents, weights, base date, arithmetic, and interpretation limits.
