About The Product Name

Structure of Product Name

Product names are assigned to our semiconductor devices using the following convention,starting with the character "M".

Assignment of Symbols

1Device Function

The device functions are classified as follows.

  • MD : DRAM
  • MR : P2ROM™, OTPROM
  • MS : Video, Memory
  • ML : Logic
  • MK : Module, Chip Set
  • MT : Driver
2Device Code

The device code expresses a function specific to a device using a combination of numbers and alphanumeric characters.

3Character Symbol

The character symbol is added to indicate the modification of an existing product, to emphasize a specification that differs from the standard specification of an existing product, or to indicate a design standard.

4Derived Code

The derived code indicates the speed ranking for DRAM products and is used as a derived code for logic products.

5Package Symbol

The package symbol expresses the type and lead bending profile of a package in two digits.

6Option Classification Symbol

The option classification symbol is used to distinguish between the option code and the package symbol.

7Option Code

The option code indicates a symbol that identifies the specification of a product with an option.
