MT40A2G4WE-083E:B

MT40A2G4WE-083E:B is a Micron DRAM memory device. It belongs to the MT40A2G4WE family and is identified by the full part number MT40A2G4WE-083E:B.
What it is in brief:
- Type: dynamic RAM (DRAM) chip used as a building block in memory modules and devices.
- Density/organization: typically a 2 Gb device with a x4 data width (2Gbit total per die with a 4-bit I/O bus; exact organization depends on the revision).
- Interface: synchronous, with a DDR-like memory interface; requires a memory controller and proper timing parameters.
- Markings: -083E indicates a specific speed/temperature/revision code; the trailing :B denotes packaging/revision variant.
Notes:
- Exact speed, voltage, timing, banks, and package vary by revision.
- For precise electrical specs, timing characteristics, and pinout, consult the MT40A2G4WE-083E:B datasheet from Micron.

Exact equivalents depend on the device specs. MT40A2G4WE-083E:B is Micron’s 2Gb×4 SDRAM in the DDR family; to cross-reference, please specify:
- SDRAM type (DDR3/DDR4/DDR2, etc.)
- speed grade (MT/s)
- voltage
- package/density
With those, I can provide precise cross-references from Hynix, Samsung, Nanya, etc.

- Pin count: 84 pins (FBGA-84 package)
- Function: Micron MT40A2G4WE-083E:B is a DDR3 SDRAM device, density 2 Gbit with x4 data width (4-bit I/O). It provides standard DDR3 signals: DQ0–DQ3 and DQS0–DQS3 for data, A0–A12 and BA0–BA1 for addressing, and control pins CS#, CK/CK#, CKE, RAS#, CAS#, WE#. Includes VDD/VSS and VDDQ/VSSQ power pins. Speeds are device-dependent (e.g., 1333/1600 MT/s).

- Manufacturer: Micron Technology, Inc.
- What kind of company: An American multinational memory and storage semiconductor company (an integrated device manufacturer) that designs and manufactures DRAM, NAND flash, and other memory products.

MT40A2G4WE-083E:B is a Micron DRAM device used as high-density system memory. Typical application areas include:
- Desktops and laptops
- Servers and data centers
- Networking equipment (switches/routers)
- Storage controllers and NVMe/SATA caches
- Graphics/compute accelerators and multimedia
- Embedded, industrial, and edge devices
All are general DDR memory usages where fast, high-capacity RAM is required.
