The Context: Micron’s M45PE series products are page-erasable 3V Series NOR flash memory devices accessed by SPI-compatible bus. The memory can be written or programmed 1 to 256 bytes at a time using the PAGE WRITE or PAGE PROGRAM command. The PAGE WRITE command consists of an integrated PAGE ERASE cycle, followed by a PAGE PROGRAM cycle.

Alliance Memory is committed to meeting its customers’ legacy component needs and has had great success working with Micron to provide continued support for a variety of devices, including 512M SDRAMs, 8G DDR3L SDRAMs, and M29F 5V flash. The company is continuing that success with these M45PE series parts, which will provide its customers with a steady supply for a minimum of two more years. In addition, Alliance Memory will be announcing a full line-up of other flash devices in Q3 2020.
