The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.
A catch-up programme will offer one or two doses to older children, depending on their date of birth:

In Asia excluding Japan, organic revenue slipped 4% for the year. Performance improved in the second half, however, with organic growth of 2% in the third quarter and 1% in the fourth quarter, reversing the first-half downturn.
然而,本轮涨价与以往周期最大的不同在于一个关键变量——HBM(高带宽内存)的爆发式增长。AI芯片(如英伟达H200/B200)对HBM的需求是传统DRAM的数倍甚至数十倍。三大原厂将大量先进制程产能转向HBM,挤占了原本用于生产手机LPDDR(低功耗内存)的产能。这种“结构性短缺”成为本轮涨价的核心推手。
