MELITA chip family

This chip family provides a characterisation platform for emerging resistive devices with a capacity of up to 1 million devices on-chip. Split into four independent sub-arrays, it contains on-chip column-parallel DACs for fast voltage programming of the DUT. On-chip readout circuits with ADCs are also available for fast read operations covering 5-decades of input current 20nA to 2mA. This allows a device's resistance range to be between 1kΩ and 10MΩ with a minimum voltage range of ±1.5V on the device.
