The IDT MX0141V memory expander. Source: IDT Integrated Device Technology, Inc. (IDT) has introduced a flash memory expander allowing designers to quadruple solid state drive (SSD) memory without the need for additional controllers.
This expander, dubbed MX0141V, is a 1:4 bidirectional multiplexer that increases memory density without the need for a larger SSD controller or a reduction in bus speeds. The expander is targeted at datacenter, enterprise and consumer memory subsystems.
By quadrupling the memory channel capability of a flash memory controller, this device reduces pin count by up to 75 percent when adding additional banks of flash. Because of this, the SSD can run faster by reducing overall loading at the memory controller and using a single memory channel to support up to four flash packages, IDT says.
Other features include a tri-state or internal pull-up for deselected ports, low multiplexer Ron resistance, low pin-to-pin output skew, ultra-low power supply current and a top/bottom PCB clam shell configuration.
