Richard Semon. Richard Semon. Richard Wolfgang Semon (22 August 1859, in Berlin – 27 December 1918, in Munich) was a German zoologist, explorer, evolutionary biologist, a memory researcher who believed in the inheritance of acquired characteristics and applied this to social evolution. He is known for coining the terms engram and ecphory .
Memetics is a theory of the evolution of culture based on Darwinian principles with the meme as the unit of culture. The term "meme" was coined by biologist Richard Dawkins in his 1976 book The Selfish Gene, [1] to illustrate the principle that he later called "Universal Darwinism". All evolutionary processes depend on information being copied ...
The term "engram" was coined by memory researcher Richard Semon in reference to the physical substrate of memory in the organism. Semon warned, however: "In animals, during the evolutionary process, one organic system—the nervous system—has become specialised for the reception and transmission of stimuli.
The theory held the controversial notion that all organic matter contains memory. History The German biologist Richard Semon linked organic memory to heredity. German physiologist Ewald Hering first suggested the idea of organic memory in an 1870 lecture for the Imperial Academy of Science in Vienna.
t. e. Memory management is a form of resource management applied to computer memory. The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is critical to any advanced computer system where more than a single ...
In operating systems, memory management is the function responsible for managing the computer's primary memory. [1] : 105–208. The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding which gets memory, when they ...
In computer science, region-based memory management is a type of memory management in which each allocated object is assigned to a region. A region, also called a zone, arena, area, or memory context, is a collection of allocated objects that can be efficiently reallocated or deallocated all at once. Memory allocators using region-based ...
A memory model allows a compiler to perform many important optimizations. Compiler optimizations like loop fusion move statements in the program, which can influence the order of read and write operations of potentially shared variables. Changes in the ordering of reads and writes can cause race conditions. Without a memory model, a compiler is ...
