Space-qualified MCMs boost memory density
New 20Mbit EEPROM multichip modules combine the latest commercial technology with proprietary radiation mitigation technology for high reliability
Maxwell Technologies has expanded its line of nonvolatile memory components with the introduction of 20Mbit EEPROM multichip modules (MCMs) that combine the latest commercial technology with proprietary radiation mitigation technology for high reliability, and die stacking technology to provide the space components industry's highest density.

Larry Longden, Maxwell's Senior Director of Product Technology, said that the new 79C2040 EEPROM MCMs incorporate 20 x 1Mbit high speed CMOS die to yield a 20Mbit module, configured as 512K x 40bit, allowing them to be used on a 32bit computer bus with 8bit of error detection and correction (EDAC).
They are available in both 3.3 and 5V versions.
'Maxwell's proprietary Rad-Pak radiation-shielding technology ensures that these modules will perform reliably in orbit or space missions, and our Rad-Stak die-stacking technology enabled us to establish a new industry standard for density', Longden said.

Longden noted that the new EEPROMs, which originally were developed to provide high-density nonvolatile memory capabilities for Maxwell's SCS750 supercomputer for space, are the latest in a series of space-qualified Maxwell component offerings incorporating the latest commercial semiconductors with the company's proprietary radiation-shielding technology.
Pricing for the 79C2040, Class K screened, begins at $9384 for quantities of 100 units.
'Producing radiation-hardened components requires a special semiconductor fabrication process and several years of development work, so components available to the space industry typically lag current commercial semiconductors by several generations', Longden explained.
'Maxwell has closed this technology gap by integrating sensitive commercial semiconductors with our proprietary radiation mitigation technology to provide 'turnkey' rad-hard space-qualified products'.
Maxwell's microelectronic products for the space market include memory modules, power modules and single board computers, all of which are fabricated in the company's QML-certified manufacturing facility in San Diego.
