I-Intel ne-AMD ngokuhlanganyela bakha isethi yemiyalo enwetshiwe ye-ChkTag (x86 Memory Tagging), ezolinganiswa ukuze isetshenziswe ngokuhlanganyela kumaphrosesa e-x86 avela kubakhiqizi abahlukahlukene. Amandla e-ChkTag afana nesandiso se-MTE (MemTag) esesivele sitholakala kuma-ARM processors futhi ivimbela ukuxhashazwa kobungozi okubangelwa ukufinyelela amabhulokhi ememori asebekhululiwe, ukuchichima kwebhafa, noma ukufinyelela inkumbulo ngaphambi kokuqaliswa.
I-ChkTag yethula imiyalelo emisha yokucubungula evumela ukubophezela kwezinga lezingxenyekazi zekhompiyutha kumathegi ezindaweni zememori kanye nokuqinisekiswa kokusetshenziswa kwesikhombi. Abahlanganisi kulindeleke ukuthi basebenzise le miyalo ukuze baqinisekise ukufinyelela okuphephile kwememori ngaphandle kokuba nomthelela ekusebenzeni kohlelo lokusebenza. Ngaphezu kwalokho, izinhlelo zokusebenza ezisebenzisa i-ChkTag zizohlala zihambisana namaphrosesa amadala antula usekelo lwezingxenyekazi zekhompuyutha ze-ChkTag, okwenza kube lula ukuqaliswa kokuvikela.
Indlela yokuvikela esetshenzisiwe ihlanganisa ukudala ithegi yebhulokhi yememori ngayinye, esebenza njengokhiye wokufinyelela kuleyo nkumbulo (isibonelo, ekusetshenzisweni kwe-MTE, umaka we-4-bit wenziwa kuwo wonke amabhayithi angu-16). Ithegi ikhiqizwa uhlelo lokusebenza lwendawo yememori eyabelwe kusetshenziswa imiyalo ekhethekile ye-CPU bese igcinwa kumabhithi angaphezulu angasetshenzisiwe esikhombi, kanye nasendaweni ebekelwe inkumbulo ewumugqa/ebonakalayo engafinyeleleki ezinhlelweni zokusebenza. Lapho ufinyelela imemori usebenzisa i-pointer emaka, iphrosesa ihlola ukuthi umaki ohlobene nesikhombisi ufana namathegi ahlobene namabhulokhi ememori futhi inikeza ukufinyelela kuphela uma amathegi ehambisana.
Ubuchwepheshe be-ChkTag bathuthukiswa njengengxenye yomsebenzi ohlanganyelwe we-Intel ne-AMD ku-EAG (x86 Ecosystem Advisory Group), eyasungulwa ngonyaka odlule ukuze ibambisane ekuqinisekiseni ukuhambisana phakathi kwamapulatifomu e-x86, ukwenza kube lula ukuxhumana phakathi kwemikhiqizo ye-Intel ne-AMD, ukwenza lula ukuthuthukiswa kwesofthiwe yezinhlelo ze-x86, kanye nokuhlonza izidingo zonjiniyela zokwandiswa kwezakhiwo. Ngaphezu kwe-Intel ne-AMD, amalungu eqembu afaka uLinus Torvalds, umdali we-kernel. Linux, uTim Sweeney, umsunguli we-Epic Games kanye nomunye wabathuthukisi ababalulekile benjini yomdlalo we-Unreal Engine, kanye nabameleli abavela ku-Broadcom, Dell, Google, Hewlett Packard, Lenovo, Meta, Microsoft, Oracle kanye neRed Hat.
Ngokungeziwe ku-ChkTag, i-Intel ne-AMD ziphinde zalinganisa futhi zahlanganisa ukuqaliswa kwe-Flexible Return and Event Delivery (FRED) imodeli yokuphazamisa yokubamba, isethi yemiyalo ye-AVX10 vector, kanye nezandiso zokuphindaphinda ze-matrix ye-Advanced Matrix (ACE).
