Ndị ọkà mmụta sayensị na Mahadum Rice emepụtala teknụzụ ebe nchekwa siri ike nke na-enye ohere maka nchekwa njupụta dị elu yana obere mmejọ kọmputa.

Ihe ncheta dabere natantalum oxide, ihe mkpuchi nkịtị na ngwa eletrọnịkị. Itinye voltaji na sanwichi graphene, tantalum, nanoporous nke nwere oke 250 nanometertantalumoxide na platinum na-emepụta ibe n'ibe ndị nwere ike ịza ebe n'ígwé na-ezukọ. Voltaji njikwa na-agbanwe ion oxygen na ohere na-agbanwe ibe n'etiti ndị na efu.

Nchọpụta nke ụlọ nyocha Rice nke chemist James Tour nwere ike inye ohere maka ihe ncheta crossbar na-echekwa ihe ruru 162 gigabits, dị elu karịa sistemụ nchekwa oxide ndị ọzọ na-enyocha nyocha nke ndị sayensị. (Bit asatọ hà otu byte; otu 162-gigabit ga-echekwa ihe dị ka gigabytes 20 nke ozi.)

Dị ka nchọpụta Tour lab nke gara aga nke ncheta silicon oxide, ngwaọrụ ọhụrụ a chọrọ naanị electrodes abụọ n'otu sekit, na-eme ka ha dị mfe karịa ncheta flash nke ugbu a na-eji atọ. "Ma nke a bụ ụzọ ọhụrụ iji mee ka ebe nchekwa kọmputa na-adịghị agbanwe agbanwe," Tour kwuru.

Ncheta ndị na-adịghị agbanwe agbanwe na-ejide data ha ọbụlagodi mgbe ike kwụsịrị, n'adịghị ka ihe nchekwa kọmputa na-enweta enweghị usoro nke na-efunahụ ọdịnaya ha mgbe emechiri igwe.

Mpempe ebe nchekwa nke oge a nwere ọtụtụ ihe achọrọ: Ha ga-agụ ma dee data na oke ọsọ ma jide dị ka o kwere mee. Ha ga-enwerịrị ike ịdịte aka ma gosipụta njide data ahụ nke ọma mgbe ha na-eji obere ike.

Njem kwuru na imewe Rice ọhụrụ, nke chọrọ 100 ugboro obere ume karịa ngwaọrụ ndị dị ugbu a, nwere ike ịkụ akara niile.

"Nke atantalumebe nchekwa dabere na sistemu ọdụ abụọ, yabụ edobere ya maka nchịkọta ebe nchekwa 3-D, ”ka o kwuru. "Ma ọ dịghịdị mkpa diodes ma ọ bụ ndị na-ahọpụta ya, na-eme ka ọ bụrụ otu n'ime ihe ncheta kachasị mfe iji wuo. Nke a ga-abụ ezigbo asọmpi maka ihe nchekwa na-eto eto na nchekwa vidiyo dị elu yana usoro ihe nkesa. "

Nhazi nke nwere akwa nwere tantalum, nanoporous tantalum oxide na multilayer graphene n'etiti electrodes platinum abụọ. N'ịmepụta ihe ahụ, ndị nchọpụta ahụ chọpụtara na tantalum oxide ji nwayọọ nwayọọ na-efunahụ ions oxygen, na-agbanwe site na ikuku oxygen, semiconductor nanoporous dị n'elu gaa na oxygen-ogbenye na ala.
