 Random access memory - Wikipedia, the free encyclopedia
Core memory, which used wires attached to small ferrite electromagnetic cores, also had roughly equal access time (the term “core” is still used by some programmers to describe the RAM main memory of a computer).
The basic concepts of tube and core memory are used in modern RAM implemented with integrated circuits.
Generally, RAM in a computer is considered main memory (or primary storage): the working area used for displaying and manipulating data.

 Dynamic random access memory - Wikipedia, the free encyclopedia
Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor.
Memory controllers in most modern PCs can typically detect, and correct errors of a single bit per 64 bit "word" (the unit of bus transfer), and detect (but not correct) errors of two bits per 64 bit word.
The BIOS in some computers, and operating systems such as Linux, allow counting of detected and corrected memory errors, in part to help identify failing memory modules before the problem becomes catastrophic.

 Method and apparatus thereof for burn-in testing of a static random access memory - US Patent 6414889
The apparatus 100 is able to test all the memory cells 122 of the static random access memories 120 in the wafer simultaneously by producing bit line currents that are matched with the current load-carrying ability of the bit lines 126 and 128.
Moreover, since the currents flowing through the bit lines 126 and 128 to the memory cells 122 are reduced (i.e., 20 µA per memory cell), the apparatus 100 could be used to test a wafer (not shown) that comprises a plurality of static random access memories 120 in a wafer burn-in test mode.
When the apparatus tests the static random access memory, the control circuit selects an appropriate number of memory cells to test and adjusts a potential of the word lines coupled to the selected memory cells to exceed a first voltage value.
