AMD pivots from HBM to LPDDR5X for new Versal Gen 2 memory on package chips
17 days ago
- AMD announces Versal Premium Gen 2 Memory on Package SoCs with on-package LPDDR5X for integrated, turn-key solutions.
- The pivot from HBM to LPDDR5X is driven by HBM supply shortages due to AI boom demand, leading to Versal HBM discontinuation.
- On-package memory strategy shift addresses long-term availability issues, as HBM has shorter production cycles than DDR technologies.
Doorways do not always cause forgetting: a multimodal investigation (2021)
16 days ago
- The study aimed to conceptually replicate the 'doorway effect' (location updating effect) using virtual and physical environments across four experiments.
- Experiments 1 and 2 used virtual reality with and without working memory load; Experiments 3 and 4 used passive video watching and active real-life movement, respectively.
- No significant effect of doorways on forgetting was observed in most experiments, except in Experiment 2 where working memory load led to increased false alarm rates for mismatched probes.
- The findings challenge the generalizability and robustness of the doorway effect, suggesting it may be more nuanced and dependent on factors like working memory load and task design.
- The study concludes that the doorway effect likely requires specific conditions to manifest, such as high cognitive interference, and may not be as robust as previously reported.
The allergy culprit histamine also boosts our memory
10 days ago
- Histamine in the brain improves memory accuracy by about 10% by enhancing novelty-linked arousal.
- The drug pitolisant, used for narcolepsy, increases brain histamine levels and boosts memory-related brain connectivity.
- Pitolisant is not recommended as a 'smart drug' due to potential sleep disruptions and long-term memory harm.
- Histamine receptors in the brain are linked to learning and memory, explaining side effects of older antihistamines.
- Research confirms histamine's role in memory applies to humans, supporting interest in treating brain conditions via histamine receptors.
- Pitolisant helps restore impaired cognitive function in diseases but does not enhance cognition beyond normal levels.

- The author recalls a memory of playing catch with his father as a teenager, which ended abruptly when a curveball hit his father in the groin.
- The father is described as a stoic, introverted geek with few friends, who lived a life marked by rationality, cynicism, and a focus on fulfilling obligations.
- He worked on the same codebase for 40 years, prioritized family commitments like attending kids' activities, and valued autonomy and honesty, often disappointed by others' failures.
- After losing his vision due to glaucoma and CRT exposure before retirement, he became dependent, which conflicted with his self-sufficient ideals, and he later died after surgery complications.
- The author reflects on rare emotional moments from his father, such as anger over a soccer game or pride during milestones, and expresses gratitude for his constant presence.
