Dual Mode(SDI) and Quad Mode(SQI) Serial interface are not common peripherals on many MCU today, Microchip’s app note (PDF) provides an alternative way to communicate with these SRAMs using existing GPIOs pins in bit-bang. This application note explains in detail the recommended usage of the SDI and SQI modes of operation of the Microchip 23XX512/23XX1024 […]

Two tubes of 23LC1024 SRAMs from Microchip
Microchip sent two tubes of mislabeled 23lc1024 SRAM chips to play with. First project is Logic Shrimp v2.
512K SRAM memory module with 13 pin interface
An open source 512K SRAM memory module for adding extra ram to your project: I have designed a very simple PCB module that allows access to 512KBytes of Static RAM. It is compatible with any microcontroller with at least 13 free digital IO pins and the ability to run from a 3.3v or 5v supply. […]
