DRAM SO-DIMM. In 2002, the United States Department of Justice, under the Sherman Antitrust Act, began a probe into the activities of dynamic random-access memory (DRAM) manufacturers in response to claims by US computer makers, including Dell and Gateway, that inflated DRAM pricing was causing lost profits and hindering their effectiveness in the marketplace.
DRAM had a 47% increase in the price-per-bit in 2017, the largest jump in 30 years since the 45% jump in 1988, while in recent years the price has been going down. [3] In 2018, a "key characteristic of the DRAM market is that there are currently only three major suppliers — Micron Technology , SK Hynix and Samsung Electronics " that are ...
A single read or write operation for the DDR4 SDRAM consists of a single 8n-bit-wide 4-clock data transfer at the internal DRAM core and 8 corresponding n-bit-wide half-clock-cycle data transfers at the I/O pins. [20] RDRAM was a particularly expensive alternative to DDR SDRAM, and most manufacturers dropped its support from their chipsets ...
Rambus DRAM was developed for high-bandwidth applications and was positioned by Rambus as replacement for various types of contemporary memories, such as SDRAM. RDRAM is a serial memory bus . DRDRAM was initially expected to become the standard in PC memory , especially after Intel agreed to license the Rambus technology for use with its future ...
