CellularRAM® Memory Boosts Mobile Performance and Value
CellularRAM® memory devices are a hybrid of the best SRAM and DRAM features, combining low power consumption, high-speed READ and WRITE functions, and lower cost. Put another way, CellularRAM memory is a pseudo-static DRAM device with an SRAM-like architecture, hidden refresh operation, and SRAM pin-compatibility. So you should choose CellularRAM memory for your low-power, cost-sensitive, and space-limited mobile designs. And CellularRAM memory die is a great choice for MCPs.

Burst A/D MUX CellularRAM Memory for Cost-Sensitive Mobile Markets
Not every mobile handset is a smartphone, and there's a huge market for basic mobile phones. Reliable, low-density, and low-pin-count burst A/D MUX CellularRAM die are excellent solutions for these low-cost, entry-level phone designs. We've developed several technical notes that will help you understand this memory type and decide whether Burst A/D MUX CellularRAM memory is right for your design.
Read more about our burst A/D MUX CellularRAM memory.
Because CellularRAM memory offers higher frequencies, synchronous operations, fast access, and variable latency initial burst access, you get high throughput and excellent performance.
And Micron CellularRAM memory is compatible with the standard wireless Flash interface. It's easy to use within an MCP with burst Flash memory, saving you design time.
Micron tests rigorously across the temperature range at wafer sort to ensure that the quality/reliability of our die is the best in the industry. Also, Micron's implementation with "2T" architecture and 6F² cell size provides very low power in the same die size. CellularRAM devices offer several power-saving features like PAR, TCR, and DPD to save power and extend battery life.
CellularRAM Features and Benefits
Features Benefits
Densities 4Mb-128Mb Available in a range of densities, provides flexibility for many designs.
Configuration x16 Available in x16 word sizes with selectable bytes and burst lengths.
Supply Voltages 1.7V-1.95V Core
1.7V-3.3V I/O A single device that can operate over an extended VCCQ range.
Power Consumption ISB = 30μA (TYP)
ICC1 = 15mA (TYP) Offers extremely low power dissipation in standby and active modes. Partial-array refresh (PAR) in standby mode provides even greater power savings.
Temperature Ranges WT: –30C to +85C
IT: –40C to +85C
AT: –40C to +105C Wide temperature range is ideal for rugged mobile and industrial environments.
Packages 48-, 54-ball VFBGA Perfect for space-limited mobile applications; at 6mm x 8mm x 1mm, the package for the 4Mb–64Mb devices is among the industry’s smallest.
Key Features for Flexibility and Power
Our CellularRAM memory is designed several unique features that fit well with the requirements of mobile applications.
Variable Latency
Cuts access time in half, making first data available as quickly as 35ns.
Fixed Latency
Enables compatibility with older systems.
Adjustable output drive
Enables users to tune outputs to match system impedance and minimize noise and power.
Partial-array refresh (PAR)
Reduces standby current by refreshing only that part of the memory array required by the host system.
On-board temperature sensor
Reduces standby current by automatically adjusting the refresh rate according to the operating temperature of the device.
Deep power-down (DPD)
Disables all refresh-related activity to reduce current consumption if the system does not require the storage provided by the PSRAM device.
