... M69AR024B SUMMARY DESCRIPTION The M69AR024B Mbit (16,777,216 bit) CMOS memory, organized as 1,048,576 words by 16 bits, and is supplied by a single 1.7V to 2.25V supply voltage range. M69AR024B is a member of STMicroelectronics 1T/1C (one transistor per cell) memory family. These devices are manufactured using dynamic random access memory cells, to minimize the cell size, and maximize the amount of memory that can be implemented in a given area ...
