An ultrasound beamformer architecture performs the task of signal beamforming using a matrix of analog random access memory cells to capture, store and process instantaneous samples of analog signals from ultrasound array elements and this architecture provides significant reduction in power consumption and the size of the diagnostic ultrasound imaging system such that the hardware build upon this ultrasound beamformer architecture can be placed in one or few application specific integrated chips (ASIC) positioned next to the ultrasound array and the whole diagnostic ultrasound imaging system could fit in the handle of the ultrasonic probe while preserving most of the functionality of a cart-based system. The ultrasound beamformer architecture manipulate analog samples in the memory in the same fashion as digital memory operates that can be described as an analog store—digital read (ASDR) beamformer. The ASDR architecture provides improved signal-to-noise ratio and is scalable.
