Taiwan's memory and AI chip stocks are booming, good news for investors as the island's market closes in on a historic milestone.

• ADATA, a big maker of memory modules, pulled in record quarterly sales — up 39% from the prior quarter and nearly four times higher than a year ago.
• The cause is simple: AI servers and data centers are soaking up memory chip supply, leaving less for PCs and phones and pushing DRAM and NAND flash prices up.
• Taiwan's stock index is a whisker from 50,000 points, with TSMC hitting a record high and preparing a large cash dividend payout.
• Winbond also set a monthly sales record for the tenth month running, though memory stocks have been soft lately as big institutions sold heavily.
• MediaTek is taking heat after reports it capped how much engineers can spend on AI tools, with one well-known analyst threatening to dump the stock over it.

Outlook: Tight memory supply should keep prices and chipmaker revenues rising, and Taiwan's index is expected to break 50,000 within days.
