タイトルまたは説明

MM23SC4442 or popularly known as 4442 module is a secured memory chip DESIGNED in Malaysia by Malaysia Microelectronic Solutions Sdn Bhd (My-MS). It is widely used in various applications for identification, access control and loyalty cards. We have shipped millions of these modules to various smart card manufacturers & end users worldwide.

 

Our MM23SC4442 is reliable & robust under normal use and handling. We are able to ship our products within reasonable delivery lead time to meet customers expectation. As the product owner, we can customize the manufacturers byte code / special header based on customers requirement. We offer high quality products at competitive prices.

 

MM23SC4442 contains 256 x 8 bits of EEPROM main memory and a 32 x 1 bit protection PROM memory. The first 32 bytes memory is irreversibly protected by the corresponding 32 protect bits in the 32 x 1 bit protection memory.  The 32 protect bits are one-time programmable and cannot be erased once they are set to logical zero. MM23SC4442 also provides a 3-bit Error Counter (EC) and three bytes Programmable Security Code (PSC) to prevent unauthorized erase/ write operation to the memory.
