ReRAM developer Weebit Nano Ltd. can show his first demo chips. In December, the foundry of the Israeli start-up delivered the first wafers with SoCs (systems-on-chip) that contain its embedded ReRAM (resistive random access memory) module. ReRAM is a non-volatile memory in which basic logic operations are implemented and which can perform arithmetic tasks.
ReRAM brings together not only main memory and mass memory, but also memory and processor and thus enables in-memory computing beyond the von Neumann computer architecture. The RAM owes its designation to its mode of operation: the memory cells, which consist of a transistor and a resistor, store their information by changing the electrical resistance of a weakly conductive substance.
Compiler fürs In-Memory Computing
The Embedded ReRAM-Modul from Weebit Nano consists of a 128 kByte ReRAM array, the control logic, a decoder, the input / output communication elements and the Error Correction Code (ECC). An analog and digital smart circuit should also improve the technical parameters of the memory array, such as speed, retention and endurance. A ReRAM compiler is also in the works.
In addition to the ReRAM module, the demo SoC itself includes a RISC-V-MCU (Microcontroller Unit), system interfaces, SRAM and peripherals. The chips that have now been completed are intended to be used for testing, characterization and evaluation by potential customers. In addition, they are used for the qualification process in the US factory of SkyWater Technology, which is to manufacture the embedded ReRAM chips in series.
