Structure of Product Name
Product names are assigned to our semiconductor devices using the following convention, starting with the character "M".
Assignment of Symbols
- Device function
The device functions are classified as follows:
MR: P2ROM, OTPROM
MS: SRAM, VRAM, FIFO
MG: Gate Array, Standard Cell
MK: Module, Chip Set
- Device code
The device code expresses a function specific to a device using a combination of numbers and alphanumeric characters.
- Character 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.
- Derived code
The device code indicates the speed ranking for DRAM products and is used as a derived code for logic products.
- Package symbol
The package symbol expresses the type and lead bending profile of a package in two digits.
- Option classification symbol
The option classification symbol is used to distinguish between the option symbol and the package symbol.
- Option code
The option code indicates a symbol that identifies the specification of a product with an option.
