Title: Luigi Penza: Innovator in Memory Architectures

Introduction

Luigi Penza is a notable inventor based in Vimercate, Italy. He has made significant contributions to the field of memory architectures, holding a total of 4 patents. His work focuses on enhancing the efficiency and stability of memory devices.

Latest Patents

One of his latest patents is the "Folded addressing method for memory architectures." This invention involves a memory circuit that includes a first and a second block of memory cells. The design features rows that cross both blocks and columns in each of the two blocks. A word decoder selects one of the rows, while a column decoder selects a set of columns from both blocks. An address splitter is utilized to pass relative portions of an address to each decoder. In one embodiment, the address splitter sends the most significant bits of the address to the word decoder and the remaining bits to a portion of the column decoder connected only to the first block. Additionally, the address splitter modifies the remaining bits using a bit subtractor, passing them to a portion of the column decoder linked solely to the second block. This method allows for efficient operation of a memory device by determining whether an address corresponds to data in the first or second block.

Another significant patent is the "Wide frequency range VCO with low jitter." This invention features a voltage-controlled ring oscillator where each starved-inverter has an associated output transfer gate. The complementary switches in the transfer gate are controlled by a frequency control voltage and a voltage difference between the supply voltage and the control voltage. The frequency produced by the oscillator is linearly proportional to the control voltage and inversely proportional to the square root of the supply voltage, enhancing noise immunity and improving frequency stability.
