Title: Mark Alexander Shand: Innovator in Memory Technology

Introduction

Mark Alexander Shand is a notable inventor based in Dampierre-en-Yvelines, France. He has made significant contributions to the field of memory technology, holding a total of 2 patents. His work focuses on methods and apparatuses that enhance the functionality and efficiency of random access memory systems.

Latest Patents

Shand's latest patents include a "Method for determining a random permutation of variables by applying a test function." This innovative method determines a random permutation of input lines that produces a permuted set of bits in a bitstream. In a source design, the method replaces a logic element whose input lines are permutable with a test function. The source design is processed by a design tool to generate the bitstream, which includes the permuted set of bits. The test function is probed with test values, and the probe results are compared with the permuted set of bits to discover the permutation of the set of bits. The test values can include a message.

Another significant patent is the "Method and apparatus for resetting a random access memory." This resettable memory apparatus includes a random access memory with multiple memory locations, each storing a plurality of bits of data. A single register has a plurality of bits, with one bit for each memory location. A reset signal resets all bits in the register to invalid. A reset value is generated when reading a particular memory location while the corresponding bit in the register is invalid, providing a resettable random access memory. Writing data to the particular memory location sets the corresponding bit in the register to valid, allowing subsequent reads to produce the data stored therein as long as the corresponding bit remains valid.
