This table provides summary of comparison of various flash memory cards, as of 2025. Of memory cards (i.e. intended as such, to use e.g. internally), SD cards allow for largest capacity by far (with SDUC variant up to 4 TB max. currently available, and the spec allocs up to 128 max.), though the much bulkier CFexpress cards can also match the ...
Mitsubishi Electric, Toshiba and NEC introduced 16 Mb DRAM memory chips manufactured with a 600 nm process in 1989. [47] NEC's 16 Mb EPROM memory chip in 1990. [47] Mitsubishi's 16 Mb flash memory chip in 1991. [47] Intel 80486DX4 CPU launched in 1994. IBM/Motorola PowerPC 601, the first PowerPC chip, was produced in 0.6 μm.
On the x86-64 platform, a total of seven memory models exist, [7] as the majority of symbol references are only 32 bits wide, and if the addresses are known at link time (as opposed to position-independent code). This does not affect the pointers used, which are always flat 64-bit pointers, but only how values that have to be accessed via ...
16 GB: DDR5 DRAM laptop memory under $40 (as of early 2024) 32/64/128 GB: Three common sizes of USB flash drives; 1 TB: The size of a $30 hard disk (as of early 2024) 6 TB: The size of a $100 hard disk (as of early 2022) 16 TB: The size of a small/cheap $130 (as of early 2024) enterprise SAS hard disk drive
(memory density) This is the total memory capacity of the chip. Example: 128 Mib. (memory depth) × (memory width) Memory depth is the memory density divided by memory width. Example: for a memory chip with 128 Mib capacity and 8-bit wide data bus, it can be specified as: 16 Meg × 8. Sometimes the "Mi" is dropped, as in 16×8.
This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has ...

A DIMM (Dual In-line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.
