The SLGNVM devices have 3V ~ 5V program/erase windows with good data retention and endurance properties. The arrays of SLGNVM devices are suitable for embedded EEPROM and flash in digital circuitries, and for the new applications of non-volatile-SRAM (nvSRAM), Non-Volatile-Register (NVR), and non-volatile FPGA (nvFPGA).","PeriodicalId":275170,"journal":{"name":"2014 14th Annual Non-Volatile Memory Technology Symposium (NVMTS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133392313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power dissipation is examined as functions of array size, leakage current of selector, and various bias schemes. The power consumption increases as the array size and the leakage current of selector increases. In addition, 1/3 bias scheme shows power consumption about 1~2 orders of magnitude larger than other bias schemes. This phenomenon is induced from the unselected cells which is delivered with voltage about Vdd/3, whereas the voltage of unselected cells are almost 0 V for 1/2 bias and floating bias schemes.","PeriodicalId":275170,"journal":{"name":"2014 14th Annual Non-Volatile Memory Technology Symposium (NVMTS)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134445488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to the multilevel capability of single layer Ta2O5 devices, 3-bit information can also be stored and read in a single device. In this report, we present a novel read scheme, allowing for distinguishing 8 different states only by using 4 different resistive states with the pulse measurements.

To fulfill these needs, a cost-effective and high-speed phase change memory cell scheme was introduced at 19nm technology node, which is directly scalable down to 1y or 1z nm nodes and can be extendable to stacked array for higher density. Here, key technologies such as self-aligned cell patterning and vertical poly-Si diode switch on metal word line were adopted. In addition, damascene Ge-Sb-Te technologies were optimized to improve programming speed and to show excellent cell performances.","PeriodicalId":275170,"journal":{"name":"2014 14th Annual Non-Volatile Memory Technology Symposium (NVMTS)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124675863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
