Alliance Memory provides drop-in replacements for 8Gb DDR3L SDRAMs

Dual-die 8Gbit DDR3L SDRAMs that are pin-for-pin drop-in replacements for and fully compatible with end-of-life, single-die 8Gb DDR3Ls from Micron Technology, have been announced by Alliance Memory.

The AS4C1G8D3LA has eight banks x 128M x eight in a 78-ball FBGA and the AS4C512M16D3LA has eight banks x 64M x 16 in a 96-ball FBGA.

“When Micron announced a last-time buy date for some of its most popular 8Gb DDR3L single-die SDRAMs, we responded by offering the original Micron part numbers, along with Alliance Memory identical replacements of the monolithic devices,” said David Bagby, president and CEO of Alliance Memory.

The DDR architecture based AS4C1G8D3LA and AS4C512M16D3LA provide speed of 10 nano seconds, fast data rates of 1866Mbits per second and clock rates of 933MHz. Operating from a single +1.35V power supply, with backward compatibility to 1.5V, the SDRAMs are optimised for main memory applications in laptops, desktops, servers, and embedded and industrial designs.

The devices are available in commercial (0 to +95 degrees C), industrial (-40 to +95 degrees C), and automotive (-40 to +105 degrees C) temperature ranges.

The AS4C1G8D3LA and AS4C512M16D3LA support sequential and interleave burst types with read or write burst lengths of four or eight. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Auto-refresh and self-refresh functions are integrated. The SDRAMs are RoHS-compliant, lead (Pb)- and halogen-free.

Alliance Memory provides critical and hard-to-find DRAM and SRAM ICs for the communications, computing, consumer electronics, medical, automotive, and industrial markets. The company’s product range includes DRAMs and SRAMs with commercial, industrial, and automotive operating temperature ranges and densities from 64kbit to 8Gbit.
