MEMOIRE ACCES ALEATOIRE [5 records]

Record 1 2008-10-27

English

Subject field(s)
  • Computer Memories
DEF

A direct access RAM which is a volatile storage whose content requires periodic refreshment.

CONT

Unlike other types of memory devices, dynamic-RAM uses only one tiny transistor per memory cell.

OBS

A binary state is represented by the presence or absence of an electric charge in each storage cell.

OBS

dynamic RAM: term and definition officially approved by the Government EDP Standards Committee (GESC).

Key term(s)
  • dynamic random access memory

French

Domaine(s)
  • Mémoires (Informatique)
DEF

Mémoire vive à accès direct qui est une mémoire volatile dont le contenu nécessite un rafraîchissement périodique.

OBS

Un état binaire est représenté par la présence ou l'absence d'une charge électrique dans chaque cellule de mémoire.

OBS

mémoire vive dynamique : terme et définition uniformisés par le Comité des normes gouvernementales en informatique.

Spanish

Campo(s) temático(s)
  • Memorias (Computadoras)
DEF

Circuito de memoria de acceso al azar que representa los estados de la memoria utilizando capacitores que almacenan descargas eléctricas.

OBS

Como los capacitores pierden eventualmente sus cargas, los circuitos DRAM deben regenerarse constantemente, de aquí el nombre de "dinámicos".

Record 2 2006-08-03

English

Subject field(s)
  • Computer Memories
DEF

A data storage device having the property that the time required to access a randomly selected datum does not depend on the time of the last access or location of the most recently accessed datum.

OBS

In microcomputers, a distinction is drawn between RAM, the contents of which can be changed by the user's program, and read-only memory (or ROM), the contents of which are fixed once and for all by the manufacturer.

OBS

random access memory; direct access storage; random access storage; RAM: terms and abbreviation officially approved by CNGI; random access memory; RAM: term and abbreviation standardized by NATO; random access storage; random access store: terms standardized by ISO.

Key term(s)
  • direct-access storage
  • direct access store
  • random-access storage
  • random memory

French

Domaine(s)
  • Mémoires (Informatique)
DEF

Mémoire dont le contenu peut être modifié en usage normal.

OBS

mémoire à accès direct; mémoire active; mémoire à accès sélectif : termes uniformisés par le CNGI; mémoire à accès aléatoire; RAM : terme et abréviation normalisés par l'OTAN; mémoire vive; RAM : terme et abréviation normalisés par l'ISO et la CSA.

Spanish

Campo(s) temático(s)
  • Memorias (Computadoras)
DEF

Dispositivo de almacenamiento auxiliar en que el tiempo de acceso para extraer los elementos de datos es constante, relativamente breve e independiente; por ejemplo, un dispositivo en que el modo (modalidad) de acceso no es secuencial como en una cinta magnética.

Record 4 1989-12-18

English

Subject field(s)
  • Semiconductors (Electronics)
CONT

The common reference to data memories is RAM (a misnomer), standing for random access memory, a name which has stuck. Data memories are normally read-write memories which may be either MOS or bipolar. (...) MOS RAMs may be either static or dynamic.

French

Domaine(s)
  • Semi-conducteurs (Électronique)
CONT

Par rapport à une mémoire MOS à accès aléatoire, les mémoires à transfert de charge présentent beaucoup moins de diffusions et de prises de contact.

Key term(s)
  • mémoire MOS à accès sélectif
  • mémoire MOS à accès direct
