Indeed, DRAM continually &#8216;forgets&#8217; and needs to be constantly refreshed. <\/li>\n<li>Flash is non-volatile, allowing you to carry data in your pocket, but is very slow and wears out. It is well-suited for data storage but can&#8217;t be used for active memory.<\/li>\n<\/ul>\n<p>&#8220;Universal memory&#8221; is a memory where the data is very robustly stored, but can also easily be changed; something that was widely considered to be unachievable until now.<\/p>\n<p>The Lancaster team has solved the paradox of universal memory by exploiting a quantum mechanical effect called resonant tunneling that allows a barrier to switch from opaque to transparent by <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lying a small voltage.<\/p>\n<p>Their new non-volatile RAM, called ULTRARAM, is a working implementation of so-called &#8216;universal memory&#8217;, promising all the advantages of DRAM and flash, with none of the drawbacks.<\/p>\n<p>In their latest work, published in <i>IEEE Transactions on Electron Devices<\/i>, the researchers have integrated ULTRARAM devices into small (4-bit) arrays for the first time. This has allowed them to experimentally verify a novel, patent-pending, memory architecture that would form the basis of future ULTRARAM memory chips.<\/p>\n<p>They have also modified the device design to take full advantage of the physics of resonant tunneling, resulting in devices that are 2,000 times faster than the first prototypes, and with program\/erase cycling endurance that is at least ten times better than flash, without any compromise in data retention.\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            &#8216;Universal memory&#8217; research passes new milestone\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                D.
