Comme montr\u00e9 sur la diapositive ci-dessous, Neo Semiconducteur ambitionne des circuits int\u00e9gr\u00e9s de 1 Tbit d\u2019ici 2030. En pratique, cela ouvrirait la voie \u00e0 des dispositifs DIMM de 2 To (deux rang\u00e9es de huit puces) assez facilement. Pour la comparaison avec de la DRAM 2D, les solutions de m\u00e9moire DDR4 plafonnent \u00e0 128 Go par module DIMM (32 circuits int\u00e9gr\u00e9s de 32 Gbit)&nbsp;; les modules DIMM de DDR5 commercialis\u00e9s actuellement proposent jusqu&#8217;\u00e0 64 Go (32 circuits int\u00e9gr\u00e9s de 16 Gbit). Reste que Samsung pr\u00e9voit des circuits int\u00e9gr\u00e9s de 32 Gbit tr\u00e8s prochainement, et que des modules de 1 To devraient voir le jour bien avant 2030 (plut\u00f4t d\u00e9but 2024).<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2023\/05\/2D3D.jpg\"><img alt=\"Image 3 : Neo Semiconductor lance sa 3D X-DRAM, de la DRAM qui ressemble \u00e0 de la flash NAND\" decoding=\"async\" width=\"999\" height=\"719\" src=\"https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2023\/05\/2D3D.jpg\" alt=\"\" class=\"wp-image-791945\" srcset=\"https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2023\/05\/2D3D.jpg 999w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2023\/05\/2D3D-300x216.jpg 300w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2023\/05\/2D3D-768x553.jpg 768w\" sizes=\"(max-width: 999px) 100vw, 999px\" \/><\/a><figcaption class=\"wp-element-caption\">\u00a9 Neo Semiconductor<\/figcaption><\/figure><\/div>\n\n\n<p>Pour sa part, Andy Hsu, fondateur et PDG de NEO Semiconductor, estime que \u00ab&nbsp;la 3D X-DRAM sera le moteur absolu de la croissance future de l&#8217;industrie des semi-conducteurs.
