Preparing For Ferroelectric Devices


The discovery of ferroelectricity in materials that are compatible with integrated circuit manufacturing has sparked a wave of interest in ferroelectric devices. Ferroelectrics are materials with a permanent polarization, the direction of which can be switched by an applied field. This polarization can be used to raise or lower the threshold voltage of a transistor, as in FeFETs, or it can c... » read more

Ferroelectrics: The Dream Of Negative Capacitance


Ferroelectrics are getting a serious re-examination, as chipmakers look for new options to maintain drive current. Ferroelectric materials can provide non-volatile memory, serving an important functional gap somewhere between DRAM and flash memory. Indeed, ferroelectrics for memory and 2D channels for transistors were two highlights of the recent IEEE Electron Device Meeting. Ferroelectri... » read more

Nonvolatile Capacitive Crossbar Array for In-Memory Computing


Abstract "Conventional resistive crossbar array for in-memory computing suffers from high static current/power, serious IR drop, and sneak paths. In contrast, the “capacitive” crossbar array that harnesses transient current and charge transfer is gaining attention as it 1) only consumes dynamic power, 2) has no DC sneak paths and avoids severe IR drop (thus, selector-free), and 3) can be f... » read more

April’19 Startup Funding: Corporate Gushers


It was another rich month for startups, large and small. In April’s top 11 funding rounds, five were investments by big corporations or corporate venture capital funds—an investor consortium led by the SoftBank Vision Fund, PayPal, Ford Motor, NTT DoCoMo, and HAPSMobile, a joint venture of SoftBank Group and AeroVironment. Those 11 investments totaled $3.74 billion. Intel Capital was als... » read more
